Treatment-related beliefs and reactions among trauma-focused therapy completers and discontinuers: A qualitative examination.

Prolonged exposure (PE) and cognitive processing therapy (CPT) for posttraumatic stress disorder (PTSD) are effective, but some patients do not respond adequately, and dropout rates are high. Patients' beliefs about treatment and perceptions of treatment components influence treatment outcomes and may be amenable to change through intervention. The present study sought to identify beliefs and reactions to PE and CPT that differentiated completers who screened negative for a PTSD diagnosis after treatment (PTSD-), completers who screened positive for a PTSD diagnosis after treatment (PTSD+), and discontinuers who attended six or fewer sessions. Thematic analysis was used to identify themes in qualitative data collected via retrospective semistructured interviews with 51 completers (19 PTSD- after treatment, 32 PTSD+ after treatment) and 66 discontinuers of PE/CPT. Participants were demographically diverse veterans across service eras. Treatment-related beliefs and reactions differentiating these groups included perceived helpfulness of treatment, self-efficacy in engaging in treatment, anticipatory anxiety and concerns, interpretations of ongoing symptoms, and perceived consequences of treatment on functioning. Further, some patterns seemed to differ in early treatment sessions compared to during the active components of treatment. Findings point to potentially malleable targets that could be intervened upon to improve trauma-focused treatment outcomes. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

Why do some people with osteoarthritis and obesity awaiting hip or knee arthroplasty achieve successful weight management? A qualitative study.

To explore perceived barriers and enablers to weight management among people with obesity awaiting total knee or hip arthroplasty. A nested qualitative study within a multi-centre, quasi-experimental pilot study comparing usual care weight management to a dietitian-led weight-loss diet. Semi-structured individual interviews were conducted with adults with end-stage osteoarthritis and a body mass index ≥30 kg/m2 waitlisted for primary total knee or hip arthroplasty. Participants with diverse sociodemographic characteristics and varied success with weight management in the pilot study were purposively sampled. Interviews were analysed using inductive thematic analysis, underpinned by constructivist-interpretivist epistemology. The Patient Activation Measure and Health Literacy Questionnaire were used for context when interpreting the findings. Twenty-five participant interviews were conducted with a sociodemographically varied sample (aged 44-80 years, 9 born in Australia, 6 in paid employment and 11 lost ≥5% of their baseline weight). Four identified themes underpinned successful weight management: beliefs, adaptability, navigating healthcare and sociocultural context. Beliefs about whether weight was perceived as a problem, the expectation of weight loss and treatment-related beliefs influenced participants' perspectives towards weight loss. Adaptability, the ability to overcome barriers to weight loss, comprised three subthemes; readiness to act, degree of independence and problem-solving skills. Approaches towards navigating healthcare influenced uptake and adherence to weight management recommendations. Importantly, these themes were dependent on social and environmental circumstances, which influenced the type of barriers experienced and resources available to the individual. Differences in a person's beliefs, their ability to adapt and navigate healthcare and sociocultural context appear to explain successful weight management among people with end-stage arthritis. Clinicians should allow for individualisation cognisant of the identified themes when providing advice and treatment to promote adherence to weight management interventions. This study explored perceived barriers and enablers to weight management among people with obesity awaiting total knee or hip arthroplasty. Four identified themes underpinned successful weight management: beliefs, adaptability, navigating healthcare and sociocultural context. Beliefs about whether weight was perceived as a problem, the expectation of weight loss and treatment-related beliefs influenced participants' perspectives towards weight loss. Understanding and assessing the contribution of each factor may guide weight management from clinicians treating patients with obesity and osteoarthritis. The data are reported using the COREQ guidelines. Patients contributed to the data collected.

Taking into Account Patient Preferences: A Consensus Study on the Assessment of Psychological Dimensions Within Patient Preference Studies.

Patient preferences are gaining recognition among key stakeholders involved in benefit-risk decision-making along the medical product lifecycle. However, one of the main challenges of integrating patient preferences in benefit-risk decision-making is understanding differences in patient preference, which may be attributable to clinical characteristics (eg age, medical history) or psychosocial factors. Measuring the latter may provide valuable information to decision-makers but there is limited guidance regarding which psychological dimensions may influence patient preferences and which psychological instruments should be considered for inclusion in patient preference studies. This paper aims to provide such guidance by advancing evidence and consensus-based recommendations and considerations. Findings of a recent systematic review on psychological constructs having an impact on patients’ preferences and health-related decisions were expanded with input from an expert group (n = 11). These data were then used as the basis for final recommendations developed through two rounds of formal evaluation via an online Delphi consensus process involving international experts in the field of psychology, medical decision-making, and risk communication (n = 27). Three classes of recommendations emerged. Eleven psychological constructs reached consensus to be recommended for inclusion with the strongest consensus existing for health literacy, numeracy, illness perception and treatment-related beliefs. We also proposed a set of descriptive and checklist criteria to appraise available psychological measures to assist researchers and other stakeholders in including psychological assessment when planning patient preference studies. These recommendations can guide researchers and other stakeholders when designing and interpreting patient preference studies with a potential high impact in clinical practice and medical product benefit-risk decision-making processes.

Therapist responsivity to patients’ early treatment beliefs and psychotherapy process.

As the conceptualization of evidence-based practice expands beyond the phasic application of treatment manuals for specific mental health diagnoses, greater attention is being paid to treatment personalization, including at its very first steps. One approach to such early personalization involves therapist flexible responsivity to patients' presenting nondiagnostic characteristics, such as their treatment-related beliefs, that are known to correlate with treatment outcomes. Such tailoring represents one element of the context-responsive psychotherapy integration framework that privileges the therapist's use of evidence-informed strategies in response to specific patient characteristics and contextual process markers (Constantino, Boswell, Bernecker, & Castonguay, 2013). In this article, we map context-responsive psychotherapy integration principles onto a psychotherapy case illustration. Namely, we describe Alice E. Coyne's attempt to navigate responsively a patient's early outcome expectation and treatment credibility perception, both of which revealed the need to change course from an original treatment plan (despite that plan making good sense vis-à-vis the patient's diagnoses and initial positive reaction to the explanation of a specific treatment protocol). In addition, the case illustrates the influence that patient treatment beliefs can have on other early therapeutic processes, such as patient change ambivalence and resistance to the therapy, that also require therapist responsivity in the service of personalization.

Medication adherence for resistant hypertension: Assessing theoretical predictors of adherence using direct and indirect adherence measures.

This study examined theoretical predictors of long-term medication adherence (i.e., treatment-related beliefs, coherence of beliefs from experience with medication, habit strength, and pill burden) for patients with apparent treatment-resistant hypertension in primary care, using a composite adherence score derived from direct and indirect measures (i.e., prescription refill, self-report, and bioanalytical assays of urine). Cross-sectional study. Individual patient records were screened for prescription refill adherence. Patients provided a urine sample for adherence screening and completed a battery of psychometric scales, including two self-report adherence measures (N=204). Convergence of adherence measures was assessed, a composite adherence score was calculated, and hierarchical multiple regression was used to examine the role of theoretical predictors of adherence. Non-adherence estimates ranged from 20.3 to 41.1%, depending on the assessment method used. Associations among adherence measures were weak to moderate (ρ=.00-.53). Medication-taking habit strength was the strongest predictor of adherence, explaining 19% incremental variance in adherence beyond treatment-related beliefs. Beliefs and coherence did not predict adherence, even for patients with weaker habits. Pill burden was not associated with habit strength or adherence for this sample. Associations among unique adherence measures were weak overall, providing further evidence that multiple measures are necessary to accurately assess adherence. Habit strength is a key predictor of adherence for chronic conditions. Both habit strength and pill burden represent important intervention targets for improving long-term medication adherence. Longitudinal inception studies are needed to properly test Common-Sense Model propositions and elucidate the role of beliefs, coherence, and habits in predicting adherence at various stages of the chronic illness trajectory. Statement of contribution What is already known on this subject? Non-adherence to antihypertensives is a leading cause of apparent treatment-resistant hypertension (aTRH). Behaviour maintenance (vs. initiation) factors may be more predictive of long-term adherence. What does this study add? Associations among direct and indirect measures of adherence are generally weak. Habit strength is the strongest predictor of long-term adherence for aTRH in primary care. Inception studies are needed to further validate Common-Sense Model propositions.

Mental health treatment-related stigma and professional help seeking among student veterans.

Record numbers of military veterans are enrolling at colleges/universities across the United States. Although a substantive subset might suffer from mental health problems, the majority of these students might not be amenable to utilizing services. The purpose of this study was to examine the role of treatment-related stigma in intentions to seek professional help among undergraduate student veterans at a university on the U.S. Gulf Coast. Focusing on 251 veterans and a gender-matched comparison group of 251 nonveterans, student veterans endorsed higher probabilities of seeking care from physicians (d = .77) and psychologists or other professionals (d = .67). In addition, nonveteran students had greater self-stigma about seeking help (d = -.27) but veterans had more negative beliefs about treatment efficacy (d = 1.07). When compared with veterans who did not exceed clinical thresholds, those with a probable need for treatment had more stigma (ds = .63). Multivariate analyses also revealed an inverse main effect of self-stigma on intentions to seek help from both professional categories. However, military experience differentially moderated associations between treatment-related beliefs and intentions to seek mental health services. Finally, exploratory analyses identified that student veterans were most likely to engage in therapy/counseling at a Veterans Affairs Medical Center or Clinic, Vet Center, or other noninstitutionally sponsored settings in the community (e.g., private practices, faith-based organizations). Looking ahead, these findings will inform research and the provision of services for addressing the mental health needs of this substantive subpopulation of college students in the United States.

Racial and Ethnic Variation in Perceptions of VA Mental Health Providers are Associated With Treatment Retention Among Veterans With PTSD.

Veterans with posttraumatic stress disorder (PTSD) who seek mental health care in the Veterans Health Administration frequently discontinue treatment prematurely. Early discontinuation of mental health treatment is more common among Veterans with PTSD who are of minority race or ethnicity. To determine whether retention in individual therapy or pharmacotherapy among Veterans with PTSD are associated with patients' ratings of their mental health providers, and if those associations differ depending on Veteran race or ethnicity. Latino, African American, and white Veterans (n=2452) who participated in a prospective national cohort study of Veterans with PTSD at the beginning of an episode of care were surveyed immediately following Veterans' PTSD diagnoses and 6 months later. Pharmacy and mental health service utilization were abstracted from Veterans Health Administration administrative databases for 6 months postdiagnosis. Retention in treatments were modeled using logistic regression among Veterans who initiated individual therapy or pharmacotherapy. Demographics, treatment need, treatment-related beliefs, treatment process measures, and ratings of mental health providers were considered as predictors. Ratings of mental health providers, more than treatment beliefs, were associated with treatment retention. Among African American Veterans, retention in pharmacotherapy was reduced if the provider was perceived as not having helped manage medication side-effects (odds ratio, 0.36; confidence interval, 0.16-0.80). All Latino Veterans but one (99% or n=64) who rated their therapist as not caring discontinued individual psychotherapy. Ratings of mental health providers were associated with treatment retention. The salience of specific provider behaviors to treatment retention varied by Veteran race or ethnicity.

Psychological distress, health and treatment-related factors among individuals initiating ART in Oromia, Ethiopia

ABSTRACTHIV diagnosis may be a source of psychological distress. Late initiation of antiretroviral therapy (ART) and treatment-related beliefs may intensify psychological distress among those recently diagnosed. This analysis describes the prevalence of psychological distress among people living with HIV (PLWH) and examines the association of recent HIV diagnosis, late ART initiation and treatment-related beliefs with psychological distress. The sample includes 1175 PLWH aged 18 or older initiating ART at six HIV clinics in Ethiopia. Psychological distress was assessed with Kessler Psychological Distress Scale. Scores ≥ 29 were categorized as severe psychological distress. Individuals who received their first HIV diagnosis in the past 90 days were categorized as recently diagnosed. Multivariable logistic regression modeled the association of recent diagnosis, late ART initiation and treatment-related beliefs on severe psychological distress, controlling for age, sex, education, area of residence, relationship status, and health facility. Among respondents, 29.5% reported severe psychological distress, 46.6% were recently diagnosed and 31.0% initiated ART late. In multivariable models, relative to those who did not initiate ART late and had longer time since diagnosis, odds of severe psychological distress was significantly greater among those with recent diagnosis and late ART initiation (adjusted OR [aOR]: 1.9 [95% CI 1.4, 2.8]). Treatment-related beliefs were not associated with severe psychological distress in multivariable models. Severe psychological distress was highly prevalent, particularly among those who were recently diagnosed and initiated ART late. Greater understanding of the relationship between psychological distress, recent diagnosis, and late ART initiation can inform interventions to reduce psychological distress among this population. Mental health screening and interventions should be incorporated into routine HIV clinical care from diagnosis through treatment.

Veterans’ Thoughts About PTSD Treatment and Subsequent Treatment Utilization

Negative thoughts about posttraumatic stress disorder (PTSD) treatment are barriers to treatment. This mixed-methods study aims to better understand beliefs about PTSD treatment and their relationship to treatment engagement. Thirty-six primary care veterans with probable PTSD reported treatment-related thoughts during a single-session cognitive behavioral therapy for treatment seeking (CBT-TS) intervention to address maladaptive treatment-related beliefs. A deductive content analysis based on the theory of planned behavior (Ajzen, 1991) and CBT concepts characterized treatment-related thoughts; exploratory quantitative statistics evaluated the relationship with subsequent treatment utilization. Behavioral beliefs about the treatment process was the most prevalent content domain. Individuals reporting automatic thoughts about treatment outcomes/process attended fewer psychotherapy sessions than individuals who did not report thoughts in that content domain. These findings increase our knowledge about cogn...

Impact of Treatment-Related Beliefs on Medication Adherence in Immune-Mediated Inflammatory Diseases: Results of the Global ALIGN Study.

IntroductionMedication adherence is critical in chronic immune-mediated inflammatory diseases (IMIDs) and could be affected by patients’ treatment-related beliefs. The objective of this study was to determine beliefs about systemic medications in patients with IMIDs and to explore the association of those beliefs and other factors with adherence.MethodsThis was a multi-country, cross-sectional, self-administered survey study. Included were adults diagnosed with one of six IMIDs receiving conventional systemic medications and/or tumor necrosis factor inhibitors (TNFi). Patients’ necessity beliefs/concerns towards and adherence to treatments were assessed by the Beliefs about Medicines Questionnaire and four-item Morisky Medication Adherence Scale. Correlation of patients’ beliefs about treatment and other factors with adherence were evaluated by multivariable regression analyses.ResultsAmong studied patients (N = 7197), 32.0% received TNFi monotherapy, 27.7% received TNFi–conventional combination therapy, and 40.3% received conventional medications. Across IMIDs, high adherence to systemic treatment was more prevalent in TNFi groups (61.3–80.7%) versus corresponding conventional treatment groups (28.4–64.7%). In at least four IMIDs, greater perception of the illness continuing forever (P < 0.001), of the treatment helping (P < 0.001), and more concerns about the illness (P < 0.01), but not clinical parameters, were associated with higher treatment necessity beliefs. Higher treatment necessity beliefs, older age, Caucasian race, and TNFi therapy were associated with high medication adherence in at least four IMIDs.ConclusionsTreatment necessity beliefs were higher than concerns about current medication in patients with IMID. Illness perceptions had a greater impact on treatment necessity beliefs than clinical parameters. Older age, greater treatment necessity beliefs, and TNFi therapy were associated with high self-reported medication adherence in at least four IMIDs.Trial registrationACTRN12612000977875.FundingAbbVie.Electronic supplementary materialThe online version of this article (doi:10.1007/s12325-016-0441-3) contains supplementary material, which is available to authorized users.

Do Concepts of Depression Predict Treatment Pathways? A Closer Look at Explanatory Models Among Clinical and Nonclinical Samples in Uganda.

Explanatory models (EMs) are a collection of beliefs about a disorder that can help us understand help-seeking and treatment pathways in diverse contexts. In 2 related studies, we explore EMs about depression held among both clinical and nonclinical samples in Uganda. To explore the potential of EMs to predict help seeking, we assessed the relationship between 2 main aspects of the EM: problem conceptualization and treatment. In Study 1, we interviewed and assessed EMs of depression for 135 lay community members and 111 professional practitioners using a vignette. In Study 2, we assessed actual EMs among 33 clinically depressed adults. We transcribed all interviews and analyzed and coded the content. In Study 1, we used logistic regression to examine the relationship of problem conceptualization and stigma to treatment choice; in Study 2, we used Fisher's exact tests to examine the relationship between conceptualization and treatment. Sociodemographics such as age, income, and language were also examined. Interviews elicited a diverse range of beliefs about the nature of depression and the types of treatment needed. However, problem conceptualization did not predict treatment in either group. Instead, education and interview language predicted treatment in clinical and nonclinical samples. Although EMs can be useful for both exploring mental health and treatment-related beliefs in clinical settings and developing mental health services, contextual factors may be more significant predictors of help seeking.

Impact of Treatment Beliefs and Social Network Encouragement on Initiation of Care by VA Service Users With PTSD

Despite the U.S. Department of Veterans Affairs' (VA) expansion of mental health services to treat VA service users with posttraumatic stress disorder (PTSD), many with PTSD do not engage in treatment. Numerous studies suggest that beliefs about treatment and social network factors, such as encouragement to seek treatment by others, affect engagement; however, prospective studies examining these factors are largely absent in this population. This study sought to understand social and attitudinal factors influencing treatment initiation, which may help to inform outreach interventions for VA service users with PTSD. A prospective, national cohort study of mental health care use among veterans recently diagnosed as having PTSD (N=7,645) was undertaken. Data from self-administered surveys and administrative databases were analyzed to assess contributions of treatment-related beliefs and social network encouragement to subsequent mental health care use, after facility, demographic, need, and access factors were controlled. After the analysis controlled for treatment need and accessibility, the odds of initiating mental health care were greater for veterans who believed that they needed help for PTSD or other emotional problems and those who were encouraged to seek help by friends and family. Beliefs about the effectiveness of PTSD treatments were associated with the type of treatment received. Negative illness identity was not a barrier to treatment initiation. VA service users' social networks, veterans' perceptions of their need for mental health care, and their beliefs about PTSD treatment effectiveness may be fruitful targets for future treatment engagement interventions.

Addressing medication nonadherence by mobile phone: Development and delivery of tailored messages

Medication nonadherence remains a significant public health problem, and efforts to improve adherence have shown only limited impact. The tailoring of messages has become a popular method of developing communication to influence specific health-related behaviors but the development and impact of tailored text messages on medication use is poorly understood. The aim of this paper is to describe an approach to developing theory-based tailored messages for delivery via mobile phone to improve medication adherence among patients with diabetes. Kreuter's five-step tailoring process was followed to create tailored messages for mobile phone delivery. Two focus group sessions, using input from 11 people, and expert review of message content were used to adapt the survey instrument on which the messages were tailored and edit the developed messages for the target population. Following established tailoring methods a library of 168 theory-driven and 128 medication-specific tailored messages were developed and formatted for automated delivery to mobile phones. Concepts from the Health Belief Model and Self-Determination Theory were used to craft the messages and an algorithm was applied to determine the order and timing of messages with the aim of progressively influencing disease and treatment-related beliefs driving adherence to diabetes medication. The process described may be applied to future investigations aiming to improve medication adherence in patients with diabetes and the effectiveness of the current messages will be tested in a planned analysis.

Correlates of Social Exclusion and Negative Labeling and Devaluation of People Living with HIV/AIDS in Rural Settings: Evidence from a General Household Survey in Zambézia Province, Mozambique

BackgroundIncreased HIV/AIDS knowledge and access to antiretroviral treatment (ART) have been hypothesized to decrease HIV stigma. However, stigma persists as a barrier to HIV services uptake. We studied the relationship between stigma, knowledge and attitudes towards HIV and its treatment, and confidence in the legal system (legal rights certitude).MethodsWe analyzed data from a household survey of 3749 randomly sampled female heads of households in 259 enumeration areas across 14 districts of Zambézia Province, Mozambique. The questionnaire included questions about beliefs, attitudes and behavior towards PLWHA, HIV transmission knowledge, treatment-related beliefs, and legal rights certitude. Factor analysis distinguished two stigma constructs: Negative labeling and devaluation (NLD) and social exclusion (SoE). Multivariable linear regression was used to determine the association between stigma, knowledge of HIV/AIDS, treatment-related beliefs, and legal rights certitude, while controlling for variance in socio-demographics.ResultsA 4-point increase in knowledge about HIV transmission was associated with more than a 3 unit decrease in NLD and SoE stigma scores (p<0.001). Given HIV transmission knowledge, a 25-point increase in legal rights certitude was associated with a 4.62 unit drop in NLD stigma (p<0.001); we did not detect an association between legal rights certitude and SoE stigma. Knowing at least one HIV positive person was associated with lower SoE (−3.17, 95% CI: −5.78, −0.56); no association with NLD (p = 0.1) was detected. ART efficacy belief was associated with higher NLD and lower SoE (2.90 increase and 6.94 decrease, respectively; p≤0.001).ConclusionIncreasing knowledge about HIV transmission and access to ART are likely to reduce stigma, but neither of the two is a panacea. Raising community awareness of the legal rights of PLWHA might improve the efficacy of stigma reduction efforts. Strategies that focus on specific domains of stigma might be more effective than generic stigma reduction strategies.

Assessing theoretical predictors of long-term medication adherence: Patients’ treatment-related beliefs, experiential feedback and habit development

Patient non-adherence to medication is a pervasive problem that contributes to poor patient health and high healthcare costs. Basic research and interventions have focused thus far on behaviour initiation factors, such as patients’ illness and treatment beliefs. This paper proposes two processes that occur after behaviour initiation that are theorised to contribute to prediction of long-term medication adherence: ‘coherence’ of patients’ beliefs from experiences with treatment and habit development. Seventy-one hypertensive patients reported their treatment-related beliefs, experiences related to treatment efficacy and medication-taking habit strength in a baseline interview. Patients then used an electronic monitoring pill bottle for approximately one month. Patients’ medication habit-strength was the strongest predictor of all adherence measures, explaining 6–27% incremental variance in adherence to that explained by patients’ treatment-related beliefs. Patients’ beliefs and experiences did not predict overall adherence, even for patients with ‘weaker’ habits. However, patients’ experiences were found to predict intentional non-adherence and habit strength was found to predict unintentional adherence. Practitioners may assess patients’ medication-taking habits to get an initial view of their likely adherence to long-term medications. Future research should assess the current theoretical predictions in a hypertension inception sample and in populations with symptomatic conditions.

Conspiracy Beliefs About HIV Are Related to Antiretroviral Treatment Nonadherence Among African American Men With HIV

Medical mistrust is prevalent among African Americans and may influence health care behaviors such as treatment adherence. We examined whether a specific form of medical mistrust-HIV conspiracy beliefs (eg, HIV is genocide against African Americans)-was associated with antiretroviral treatment nonadherence among African American men with HIV. On baseline surveys, 214 African American men with HIV reported their agreement with 9 conspiracy beliefs, sociodemographic characteristics, depression symptoms, substance use, disease characteristics, medical mistrust, and health care barriers. Antiretroviral medication adherence was monitored electronically for one month postbaseline among 177 men in the baseline sample. Confirmatory factor analysis revealed 2 distinct conspiracy belief subscales: genocidal beliefs (eg, HIV is manmade) and treatment-related beliefs (eg, people who take antiretroviral treatments are human guinea pigs for the government). Both subscales were related to nonadherence in bivariate tests. In a multivariate logistic regression, only treatment-related conspiracies were associated with a lower likelihood of optimal adherence at one-month follow-up (odds ratio = 0.60, 95% confidence interval = 0.37 to 0.96, P < 0.05). HIV conspiracy beliefs, especially those related to treatment mistrust, can contribute to health disparities by discouraging appropriate treatment behavior. Adherence-promoting interventions targeting African Americans should openly address such beliefs.

Providing a treatment rationale for PTSD: Does what we say matter?

Little is understood about the factors that influence a woman's preference for a particular type of treatment after an assault. Furthermore, it remains unclear the extent to which providing detailed information such as the mechanism underlying a treatment or its side effects can affect a client's treatment preference for psychotherapy or pharmacotherapy. The current study of 324 women with varying degrees of trauma exposure and posttraumatic stress symptoms experimentally manipulated the content of treatment rationales for two common PTSD treatments: sertraline (SER) and prolonged exposure (PE). Specifically, both information regarding the hypothesized mechanism of the treatment and treatment side effects were manipulated. In general, personal reactions were more positive and credibility was stronger for psychotherapy than pharmacotherapy. This preference for the psychotherapy persisted regardless of specific information presented in the treatment rationale. For those reporting heightened hyperarousal and those of minority status, there was an increased likelihood of more positive reactions to sertraline. The results highlight assessment of treatment-related beliefs and preferences early on in the therapeutic process. Ultimately, understanding the factors that shape treatment preferences may contribute to the development of personalized treatment strategies that integrate preferences and attitudes about treatment as a way of bolstering adherence and outcome.

What you believe is what you want: Modeling PTSD-related treatment preferences for sertraline or prolonged exposure

Despite the known efficacy of various psychotherapies and pharmacotherapies for posttraumatic stress disorder (PTSD), we know little about what factors predict treatment preference. In the present study, we first developed exploratory path models of treatment preference for a psychotherapy or pharmacotherapy ( n = 273) and then conducted confirmatory analyses of these models in a second sample ( n = 324) and in a third generalization sample of trauma-exposed women ( n = 105). We examined demographic and psychopathology factors and treatment-related beliefs (i.e., credibility and personal reactions). Across all samples, treatment-related beliefs were the strongest predictors of treatment preference. Further, severity of depression directly reduced the likelihood of choosing psychotherapy, and severity of PTSD directly increased the likelihood of choosing pharmacotherapy. These results underscore the importance of better understanding individual's beliefs regarding treatments. With a clearer understanding of these factors, we may be able to reduce barriers to treatment and increase access to effective treatments for those with trauma-related symptoms.

HIV Treatment Beliefs and Sexual Transmission Risk Behaviors among HIV Positive Men and Women

People are living longer and healthier with HIV infection because of successful combination antiretroviral therapies. HIV treatment beliefs are often associated with sexual practices among people living with HIV/AIDS but these associations may depend on the HIV status of sex partners. In a sample of 158 HIV positive men and women who were receiving HIV treatments, we examined the association between HIV treatment beliefs, HIV transmission risk perceptions, medication adherence, viral load and engaging in unprotected intercourse with any sex partners and specifically with sex partners who were not HIV positive (non-concordant). Results showed having missed medications in the past two days and treatment-related beliefs were significantly associated with engaging in unprotected intercourse with all sex partners as well as non-concordant partners. However, multivariate models showed that only treatment beliefs were significantly associated with engaging in unprotected intercourse with non-concordant partners. These results extend past research by demonstrating that the HIV status of sex partners sets the context for whether prevention-related treatment beliefs are associated with HIV transmission risk behaviors among people living with HIV/AIDS.

Decision-making strategies for patients with localized prostate cancer.

Patients diagnosed with early-stage prostate cancer not only have to cope with the impact of the cancer diagnosis, but also need to interpret complicated medical information to make an informed treatment decision. We report initial results from an ongoing longitudinal investigation examining treatment decision making among men diagnosed with early stage prostate cancer. Men (N = 654) were recruited into the assessment study after an initial treatment consultation with a urologic surgeon or radiation oncologist. Patients were, on average, 66 years old, married (85%), had at least a high school education (45%), were retired (58%), and were Caucasian (91%) or African American (7%). Guided by a cognitive-affective theoretical framework, we assessed treatment and disease-relevant beliefs and affects in addition to clinical variables. The majority of patients decided on external beam radiation therapy (52%), followed by brachytherapy (25%), prostatectomy (17%), and watchful waiting (6%). Patients who decided on prostatectomy were significantly younger (mean age, 58 yr) than patients who received radiation therapy (mean age, 67 yr) and brachytherapy (mean age, 66 yr). When asked for the most important reason influencing their treatment decision, patients indicated physician recommendation (51%), advice from friends and family (19%), information obtained from books and journals (18%), or the Internet (7%). Among cognitive variables, patients who decided on surgery perceived prostate cancer as being significantly more serious (P <.001), and had greater difficulties in making a treatment decision (P <.005) compared with patients receiving radiation therapy or brachytherapy. Surgical patients were also more distressed about their treatment decision (P <.001) and concerned that the cancer might spread (P <.005). To date, patients followed-up after treatment have not indicated significant regrets about their therapeutic choice. These data suggest that unique treatment-related beliefs and affects need to be taken into account during the treatment counseling process. Implications for the development of decision aids are discussed.
