We reviewed randomized controlled trials (RCTs) that examined the effects of psychological interventions on HIV disease markers including neuroendocrine hormone regulation and immune status. Utilizing both PubMed and PsycINFO, we searched for RCTs published over the past 20 years (1987–2007). Of the 31 RCTs identified, 14 tested effects of psychological interventions on neuroendocrine regulation or immune status. Despite the fact that there are significant methodological limitations of RCTs that have been conducted to date, psychological interventions for HIV-positive persons have been shown to be efficacious in improving psychological adjustment compared with wait-list or treatment as usual control conditions. However, there is little support for differential efficacy of group-based interventions that have been tested to date, even in comparison with semistructured social support groups. Irrespective of the treatment modality, it seems that interventions that are successful in improving psychological adjustment are more likely to have salutary effects on neuroendocrine regulation and immune status. Psychological interventions represent a viable adjuvant treatment that can assist patients with improving psychological adjustment and potentially enhancing immune status. To inform the development of innovative treatments with potentially superior efficacy, deconstruction trials are necessary to examine the effects of distinct components of multimodal psychological interventions compared with nonspecific social support effects. Effectiveness trials of promising psychological interventions with more representative samples of HIV-positive persons are also needed to provide more definitive information on the clinical utility and potential cost-effectiveness of treatments that have been developed to date.

It has been well established that persons with HIV infection have high rates of stressful life events and dysphoria (1). HIV presents individuals with multiple challenges, which may overwhelm their coping resources and impair psychological adjustment to the ongoing demands of managing this stigmatized, chronic illness (2,3). Depressive symptoms and stress have been linked to HIV disease progression (4). On the other hand, positive psychological states, such as positive affect and finding benefits in living with a chronic illness, promote resilience in the face of negative life events, facilitate more effective management of HIV infection, and independently predict less rapid HIV disease progression (5–10). Consequently, psychological interventions designed to improve psychological adjustment (i.e., decrease negative affect as well as enhance positive psychological states) may encourage behavior change, modulate stress physiology, and slow HIV progression (11,12). However, consistent with the broader literature on the effects of psychological interventions on immunity (13), there are significant methodological limitations of the randomized controlled trials (RCTs) that examined the efficacy of psychological interventions on HIV disease markers. The goal of this paper is to review RCTs examining the efficacy of psychological interventions on neuroendocrine hormone regulation and immune status to provide recommendations for future research in this area.

Although ongoing monitoring of the T-helper (CD4+) cell count and viral load are part of the standard of care for the medical management of HIV infection, long-term follow-up is often necessary to observe clinically meaningful changes (14). Other measures may provide important information regarding the capacity of the immune system to defend against certain opportunistic infections and cancers. For example, the ability of lymphocytes to multiply when challenged by antigens, evaluated by testing proliferative responses to plant mitogens such as phytohemagglutinin (PHA), may partially compensate for declines in CD4+ cells as HIV progresses (15). It is also noteworthy that individuals with acquired immune deficiency syndrome (AIDS) who remain healthy despite having critically low CD4+ cell counts display a relative preservation of natural killer (NK) cells and natural killer cell cytotoxicity (NKCC), innate immune parameters which are important for the surveillance of pathogens and neoplasias (16). Finally, HIV-positive persons are commonly coinfected with a variety of other viruses that may accelerate HIV replication and directly contribute to the development of AIDS-related conditions (17). Increases in immunoglobulin G (IgG) antibodies indicate decrements in cellular-mediated immune control over latent viral infections, such as Epstein-Barr virus (EBV), po-tentially placing individuals at increased risk for more rapid HIV disease progression (18).

Interventions for HIV-positive persons that successfully improve psychological adjustment may enhance immune status by modulating neuroendocrine hormone regulation (12). Several adrenal hormones—including cortisol and catecholamines—are known to be altered by modifiable psychological factors, such as cognitive appraisals and coping responses (19). More effective regulation of neuroendocrine hormones may predict improvements in various indices of immune status that retard the onset of disease complications in HIV-positive persons (20). This is supported by findings indicating that elevated cortisol impairs cellular immunity (21–24) as well as predicts faster progression to AIDS and mortality (25). Other investigations have observed that higher concentrations of norepinephrine (NE) promote in vitro elevations in HIV viral load (26), and higher autonomic nervous system activity at rest before beginning highly active antiretroviral therapy (HAART) predicts poorer suppression of HIV viral load and decreased CD4+ cell reconstitution (27).

Utilizing both PubMed and PsycINFO, we searched for RCTs in HIV/AIDS published over the past 20 years (January of 1987–June of 2007) with the following key words: adherence, anger, anxiety, bereavement, cognitive-behavioral, coping, depression, intervention, positive affect, relaxation, and stress management. Of the 31 RCTs identified, we focused on the 14 that examined psychological intervention effects on neuroendocrine hormone regulation or immune status. These included RCTs of cognitive behavioral, relaxation and meditation, and emotional expression interventions (Table 1).

  		TABLE 1. Randomized Controlled Trials of Psychological Interventions for HIV-Positive Persons that Examined Neuroendocrine or Immune Outcomes

 

Cognitive-Behavioral Interventions
A large proportion of psychological interventions for HIV-positive persons employ cognitive-behavioral techniques (28). By promoting enhanced awareness of cognitive appraisals of stressors and teaching cognitive restructuring, cognitive-behavioral therapy improves emotion regulation and reduces maladaptive behaviors (29). Cognitive-behavioral stress management (CBSM) is one of the more common of these interventions (30,31). CBSM is a 10-week, group-based intervention that incorporates training in cognitive-behavioral therapy, coping skills, interpersonal skills, and relaxation techniques (e.g., progressive muscle relaxation, guided imagery, autogenics, and meditation).

Cognitive-behavioral interventions for HIV-positive persons are efficacious in reducing negative affect when compared with wait-list or treatment as usual controls (32–44). However, cognitive-behavioral treatments for HIV-positive persons have not demonstrated superior efficacy in reducing negative affect compared with other interventions (e.g., interpersonal therapy) or semistructured social support groups (33,35,45). Overall, cognitive-behavioral interventions that reduce negative affect tend to show improvements in HIV disease markers. In RCTs where cognitive-behavioral interventions were unsuccessful in improving psychological adjustment or where they were compared with other active treatments, no effects on immune status were observed.

RCTs have examined the efficacy of cognitive-behavioral interventions that are tailored to meet the needs of individuals at various points in the experience of HIV infection (e.g., serostatus notification, early emergence of symptoms). In addition to the potential psychological benefits of addressing the unique challenges at distinct stages of HIV infection, RCTs conducted at discrete points in the disease experience may provide insight into the most optimal timeframe(s) where interventions may influence immune status. For example, it is plausible that intervention effects on immune status are more reliably observed among individuals in the earlier stages of HIV infection where the immune repertoire is largely intact and responsive to psychological changes. On the other hand, psychological interventions may also be effective with HAART- treated individuals, given the ability of these medications to markedly slow rates of viral replication and immune decrements. The cognitive-behavioral interventions outlined in Table 1 were delivered at various stages of HIV infection. Our discussion of these RCTs will be organized by HIV stage.


HIV Serostatus Notification
In the initial trial of CBSM, gay men who did not know their HIV serostatus were randomized to group-based CBSM, group-based aerobic exercise, or an assessment-only control (40,46). After 5 weeks, men provided blood samples for HIV antibody testing and were informed of their serostatus 72 hours later. Among HIV-positive men, controls showed significant increases in anxiety and depression, whereas those in the CBSM and aerobic exercise groups reported no changes. HIV-positive men in CBSM displayed significant increases in CD4+ cell counts, NK cells, PHA lymphocyte responses, and NKCC pre- to post notification. Controls showed concurrent decrements in NK cell counts, PHA lymphocyte responses, and NKCC (40). Thus, these findings provided some preliminary evidence that psychological interventions could modulate immunologic parameters in parallel with changes in mood even at the very earliest points in the disease process.

Coping With Asymptomatic HIV Infection
The period after HIV serostatus notification can also be stressful despite the absence of overt symptoms as individuals face an unpredictable disease course. Psychological interventions may assist asymptomatic persons in coping with this uncertainty. Cleary and colleagues examined the effectiveness of a group-based intervention that provided cognitive-behavioral coping skills training to increase social support and promote behavior change in a diverse sample of newly diagnosed blood donors (43). Compared with a community referral control, no intervention effects on depressive symptoms or CD4+ counts were observed at 1-year follow-up. However, only 38% of those randomized to the intervention attended any group sessions. The lack of effects on immune status may be attributable to the fact that this intervention was unsuccessful in reducing depressive symptoms. This is supported by the results of another RCT where no differences in CD4+ cells or T-cell proliferative responses were observed between cognitive-behavioral and supportive-expressive groups that were equally efficacious in reducing distress (33,47). Men in both interventions who reported greater reductions in distress showed smaller CD4+cell count declines over 2 years (47). In other work, Coates and colleagues examined the efficacy of a behavioral stress reduction group in gay men (38). Compared with a wait-list control, no intervention-related changes in CD4+ cells, NK cells, or PHA lymphocyte responses were observed during the intervention. Mood effects were not examined (38). Overall, findings suggest that immunologic effects are unlikely if interventions fail to improve psychological adjustment.

Managing the Emerging Symptoms of HIV Infection
The onset of symptoms of HIV infection can result in increased anxiety and depression as well as a resurgence of traumatic ideation from diagnosis. Psychological interventions may provide an opportunity for individuals to acquire new skills for coping with the emergence of symptoms. In one RCT, mildly symptomatic gay men were randomized to CBSM or a modified wait-list control condition (34,41,48). Men in the modified wait-list control were invited to attend a 1-day seminar after the 10-week intervention period. Findings indicated that men in CBSM reported decreases in depressive symptoms, anxiety, and mood disturbance as well as increases in cognitive coping and perceived social support during the intervention. Effects of CBSM on the use of adaptive cognitive coping strategies (acceptance and positive reframing) and perceived social support mediated reductions in distress during the 10 weeks (34). Increases in the use of positive reframing during CBSM also mediated reductions in depressive symptoms over a 6-month follow-up (39). The psychoneuroimmunologic framework underlying the RCTs of CBSM proposes that mood improvements are related to potentially immunomodulatory hormonal changes (12). This seemed to be the case with men in these CBSM groups showing decreases in 24-hour cortisol and NE, reductions in the plasma cortisol/dehydroepiandrosterone-sulfate (DHEA-S) ratio, and increased plasma testosterone (48–52). Reductions in NE paralleled decreases in anxiety (48). Decreases in urinary cortisol and plasma cortisol/DHEA-S as well as increased plasma testosterone paralleled decreases in depressed mood (49–52).

Men randomized to CBSM also displayed improved antiviral and cellular immunity compared with those in the modified wait-list control (41,53,54). CBSM decreased herpes simplex virus type 2 (HSV-2; genital herpes) IgG titers during the intervention and buffered against increases in EBV IgG titers through a 6- to 12-month follow-up. The effect of CBSM on HSV-2 IgG titers was partially mediated by reductions in depressive symptoms as well as increases in social support (41, 53), whereas CBSM effects on EBV IgG titers paralleled sustained increases in social support (54). CBSM also buffered against declines in cytotoxic-suppressor (CD8+) T cells at 1-year follow-up; this was mediated by greater reductions in NE during the intervention (48). Finally, men in CBSM displayed increases in transitional naïve T cells through 1-year follow-up (55), an effect mediated by decreases in depressive symptoms and 24-hour cortisol during the intervention (52). Although findings from these studies were based on different cohorts of men in this RCT, tests of mediation generally indicate that improvements in psychological adjustment are a key determinant of intervention effects on neuroendocrine hormone regulation and immune status.

Coming to Terms With AIDS
Even in the HAART era, individuals living with AIDS grapple with existential challenges related to declines in functional status and health-related quality of life as well as the ever present threat of mortality (56,57). One trial examined the efficacy of a CBSM intervention that included components of supportive/expressive therapy (SET) to promote the expression of negative emotions and detoxify issues related to death and dying in women with AIDS (58). Compared with an attention-matched control that watched educational videotapes, no effects of CBSM+SET were observed on CD4+ cell counts or HIV viral load during the 10-week intervention. CBSM+SET effects on psychological adjustment were not examined, but increases in self-efficacy during the intervention period were associated with concurrent increases in CD4+ counts and declines in HIV viral load.

Bereavement interventions assist HIV-positive individuals with managing grief and distress associated with the loss of a loved one to AIDS. Goodkin and colleagues observed that a group-based bereavement intervention for HIV-positive and HIV-negative gay men was efficacious in reducing grief and distress during the 10-week intervention period compared with a community referral condition (44). HIV-positive men in the bereavement intervention displayed reductions in plasma cortisol and reported fewer healthcare visits through a 6-month follow-up (59). Significant intervention effects were reported for CD4+ counts over the same period. However, among the subsample of HIV-positive men, there were no intervention effects on CD4+ counts at follow-up. Interestingly, higher plasma cortisol was associated with lower CD4+ cell counts among HIV-positive men. There were no concurrent intervention effects on the ratio of CD4+ to CD8+ cells (CD4:CD8). Other findings indicated that control participants displayed increases in HIV viral load during the intervention whereas men in the bereavement intervention showed no change (60). Although interventions seem to assist HIV-positive individuals in coping with bereavement, Sikkema and colleagues have observed that women and individuals who are at risk for a complicated bereavement seem to derive the most psychological benefit (61,62). Future RCTs should examine the efficacy of bereavement interventions in these populations.

Managing HAART Regimens
HAART is a demanding, unforgiving treatment regimen that requires unprecedented levels of patient adherence to maximize the clinical benefits (63,64). Interventions that focus exclusively on enhancing HAART adherence have been shown to be efficacious (65). Two RCTs examined whether including cognitive-behavioral interventions to improve psychological adjustment enhances the long-term efficacy of HAART adherence interventions as reflected in control of viral load (42,66,67). Antoni and colleagues sought to determine whether there was any added benefit to providing CBSM in combination with medication adherence training (MAT) compared with MAT alone in a sample of HAART-treated gay men. CBSM+MAT decreased depressed mood and denial coping over the 10-week intervention but there were no effects on self-reported adherence (42). No intervention effects on immune status were observed in intent-to-treat analyses. However, in a subsample of the men who had detectable viral load at baseline (n = 101), those in CBSM+MAT displayed a statistically significant and clinically important decrease in HIV viral load (0.56 log10) through 15 months post randomization. Reductions in depressed mood during the intervention mediated the sustained effect of CBSM+MAT on HIV viral load after controlling for self-reported HAART adherence (66). Lending support to these findings, Safren and colleagues examined the efficacy of a 12-week individual cognitive-behavioral intervention for adherence and depression in depressed men and women. Over the intervention period, individuals in the cognitive-behavioral treatment reported reductions in depressive symptoms and displayed increases in electronically monitored HAART adherence compared with those who received a single adherence intervention session (67). Participants in the cognitive-behavioral intervention also displayed decreases in HIV viral load through a 9-month follow-up, but due to the crossover trial design there was no comparison condition. Taken together, these RCTs support the efficacy of cognitive-behavioral treatments in combination with problem-focused HAART adherence interventions.

Is Interpersonal Therapy Superior to Cognitive-Behavioral Therapy?
One RCT examined the efficacy of four individual interventions with depressed men and women who were at various stages of HIV infection (45). Individuals randomized to interpersonal therapy and supportive therapy with imipramine displayed greater reductions in depressive symptoms and increases in physical functioning over the 16-week intervention period compared with either cognitive-behavioral therapy or supportive therapy alone. However, no group differences in CD4+ count were observed over the 16 weeks. Because the association between distress and cellular immunity is most reliably observed in individuals with low viral burden (68), the fact that a substantial minority of participants in this pre-HAART era RCT were at advanced stages of HIV disease may have obscured any effects on immune status. The small sample in each treatment arm and the lack of long-term follow-up also make interpretation of negative effects for CD4+ count difficult. RCTs are needed to examine the differential efficacy of interpersonal and cognitive-behavioral approaches in HAART-treated persons, especially those who present with clinical depression.

Relaxation and Meditation
Relaxation training and meditation-based interventions may improve psychological adjustment, decrease physiologic arousal, and enhance immune status among HIV-positive persons (69–73). One RCT observed that asymptomatic gay men in a 10-week relaxation training program (progressive muscle relaxation, biofeedback, meditation, and hypnosis) reported reductions in distress and anxiety during the intervention compared with an assessment-only control (69). Intervention effects on distress paralleled concurrent increases in CD4+ counts, but no group differences were observed at post intervention. In another small RCT, Auerbach and colleagues determined that symptomatic gay men in an 8-week relaxation training group (thermal biofeedback, guided imagery, and hypnosis) reported increases in vigor and hardiness as well as decreases in HIV-related symptoms during the intervention compared with a wait-list control (70). No concurrent effects on negative affect or CD4+ counts were observed over this short follow-up period (70).

Relatively little is known about the differential efficacy of distinct forms of relaxation training or meditation. Eller examined 6-week progressive muscle relaxation or guided imagery interventions delivered to men and women via audiotape after brief face-to-face instruction (71). Compared with an assessment-only condition, progressive muscle relaxation reduced depressive symptoms and increased CD4+ counts while guided imagery decreased fatigue (an important HIV-related symptom) during the intervention (71). Diego and colleagues also examined the efficacy of a 12-week progressive muscle relaxation intervention compared with a 12-week massage therapy intervention in adolescents (73). Both treatments were delivered twice a week in 20-minute sessions. Participants in both conditions reported reductions in anxiety, but only the massage therapy group reported reductions in depressive symptoms during the intervention. Decreases in depressive symptoms were paralleled by concurrent increases in NK counts, NKCC, CD4+ counts, and CD4:CD8 in the massage therapy group only. Results support the efficacy of massage therapy, but progressive muscle relaxation may not have been delivered with the frequency necessary to reduce depressive symptoms (71). Although further research is necessary to examine the efficacy of distinct forms of relaxation training or meditation, findings from these small RCTs indicate that interventions that successfully reduce depressive symptoms seem to be more likely to enhance immune status. RCTs of mindfulness-based stress reduction are currently being conducted and these may provide further data regarding the efficacy of relaxation and meditation interventions with HIV-positive persons.

Written Emotional Expression Interventions
Investigations with healthy populations support the efficacy of writing about stress and trauma (written emotional expression) for improving psychological adjustment and immune status (74). Written emotional expression provides an opportunity for individuals to confront traumatic experiences and it may create positive outcome expectancies for emotion regulation (75,76). In a small HAART era RCT, HIV-positive men and women were randomized to four sessions of writing about their worst stressful event or writing about trivial daily events (77). Those writing about their worst stressor had reduced HIV viral load at 2 weeks post randomization and increased CD4+ counts over a 6-month follow-up compared with the trivial writing control. More definitive RCTs of written emotional expression are needed to replicate these findings.

Summary
Of the 14 RCTs that were examined in this review, seven RCTs observed intervention effects on HIV disease markers. Consistent with RCTs examining whether psychotherapy prolongs survival in patients with various types of cancer (78), interventions that do not successfully improve psychological adjustment may be less likely to enhance immune status among HIV-positive persons. Three of the seven RCTs that reported negative findings for immune status either did not examine or found no evidence indicating intervention effects on any indicator of psychological adjustment (38,43,58). Although two of the RCTs with negative findings did observe improvements in some indicators of psychological adjustment, these interventions did not reduce depressive symptoms (70,73). Depressive symptoms have been linked to more rapid HIV disease progression across a number of studies (4), but it would be premature to state that reductions in depressive symptoms are necessary for psychological interventions to influence HIV disease markers. Of the two remaining RCTs with negative findings, one compared two interventions that were equally efficacious in reducing depressive symptoms with a small sample that was not powered to detect differences in immune status between two active treatments (33,47). The last RCT where null findings were reported was conducted in the pre-HAART era (45), and the fact that a substantial minority of participants were at advanced stages of HIV disease may have obscured any intervention effects on immune status. This highlights that improvements in psychological adjustment may be necessary but not sufficient for interventions to have salutary effects on immune status. Future RCTs should closely attend to inclusion criteria in order to enroll cohorts that are more likely to display changes in HIV disease markers that may be linked to intervention-related effects on psychological adjustment (66).

Although it seems that psychological intervention effects on immune status were more reliably observed among individuals at the earlier stages of HIV infection, only one published RCT has examined the efficacy of an intervention for individuals living with AIDS (58), thereby making comparisons by disease-stage hazardous. Although individuals may meet criteria for AIDS based on medical history, substantial improvements in immune status among those taking HAART may increase the responsiveness of the immune system to changes in psychological adjustment. Interestingly, two of the three RCTs conducted in the HAART era reported that psychological interventions enhanced immune status in samples that were diverse with respect to HIV disease stage (66,73,77), but conclusions based on such a small number of trials would be premature. Because HIV-positive persons continue to endure a chronic, unpredictable disease with increased burdens related to managing HAART regimens, psychological interventions represent a viable adjuvant treatment that can assist patients with improving psychological adjustment and potentially enhancing immune status.

Limitations and Directions for Future Research
There are numerous methodological limitations of the RCTs reviewed above. The major limitation is the lack of clarity regarding the active element(s) of these multimodal interventions. For example, in two RCTs of CBSM, greater home relaxation practice was associated with mood improvements, increases in immune parameters, and decreases in salivary cortisol (41,79,80). Although these findings are provocative, it is difficult to determine whether they support the efficacy of the relaxation training component of CBSM or if they are a marker for better adherence to the overall intervention protocol. Deconstruction trials are necessary to examine the efficacy of distinct components of psychological interventions in comparison with nonspecific social support effects. The vast majority of RCTs did not include attention-matched control conditions. Without an attention-matched control, it is difficult to determine whether the effects are specific to these interventions or nonspecific effects of any psychological treatment. Bearing in mind that the magnitude of intervention effects on psychological adjustment is variable across the six RCTs included in this review that provided sufficient descriptive data to calculate an effect size statistic (Cohen’s d range = 0.11 to 0.54; median = 0.31), deconstruction trials may inform the development of innovative interventions for HIV-positive persons with potentially superior efficacy. Deconstruction trials should also specifically examine what aspects of stress and coping interventions cultivate positive psychological states (11,81–84), and if components of these treatments that modify positive psychological states influence HIV disease markers.

Future efficacy trials of psychological interventions for HIV-positive persons should also attempt to improve on the numerous methodological limitations that are evident in RCTs that have been conducted to date. Most trials examined the effects of psychological interventions with small samples and it is possible that many did not have the power necessary to detect effects on immune status. However, effect size estimates for the six RCTs that included sufficient descriptive data to compute this statistic generally indicated a lack of intervention effects on CD4+ counts (Cohen’s d range = –0.77 to 0.31; median = –0.17). Because of the heterogeneity of other HIV disease markers examined, it was not possible to calculate reliable estimates for the effect size range. It is noteworthy that only six trials have examined the sustained effects (beyond the immediate postintervention assessment) of psychological interventions on measures of immune status. Changes in immune status may emerge over longer periods and future RCTs with sufficient power should include long-term follow-up assessments to conduct more definitive tests of intervention effects on HIV disease markers. This is supported by findings from an RCT of CBSM + MAT where clinically important reductions in HIV viral load emerged over a long-term follow-up (66). Including follow-up assessments will also be crucial to examine the effects of psychological interventions on clinically relevant outcomes, such as progression to AIDS and mortality. Whereas enhanced immunosurveillance may have implications for protection against future development of opportunistic infections and neoplasias (12), no investigation to date has reported intervention effects on clinically relevant outcomes. An important first step may be examining well-defined pathophysiological pathways such as progression of virally initiated neoplasias, which has been associated with elevated life stress (85).

It is also noteworthy that the majority of RCTs examining the effects of psychological interventions have been well-controlled efficacy trials with extensive exclusion criteria that were conducted mostly with gay men. Although there is some support for the efficacy of cognitive-behavioral interventions with HIV-positive women (86,87) and heterosexual men (32), it is worth examining whether treatments that intervene at the family level will demonstrate superior efficacy for these groups (88–90). It is clear that there is a need for more trials examining the efficacy of psychological interventions for women and heterosexual men living with HIV/AIDS. In addition, the stringent inclusion criteria of well-controlled efficacy trials limit the external validity of intervention effects that have been observed. Despite the fact that a substantial minority of HIV-positive persons have comorbid substance use disorders (91), these individuals have commonly been excluded from previous efficacy trials of psychological interventions. Future investigations should develop and test innovative psychological interventions that are designed to meet the unique needs of substance users. In particular, individuals who regularly use stimulants, such as cocaine and methamphetamine, may be good candidates for psychological interventions because they are more likely to be nonadherent to HAART and display poor suppression of HIV viral load (92,93).

Finally, despite the past 20 years of research to develop and test the efficacy of innovative psychological interventions for HIV-positive persons, there are insufficient data regarding the clinical relevance and policy implications. It is unclear to what extent these treatments are being implemented in the context of regular medical care or at community-based organizations.

Another important, unanswered question is whether psychological interventions can be tailored to meet the needs of individuals living with HIV/AIDS in the developing world to improve psychological adjustment and immune status. Effectiveness trials of promising psychological interventions with more representative samples of HIV-positive persons in varied settings are needed to provide more definitive information on the clinical utility of these treatments and their potential cost-effectiveness.
