RESUMEN

BACKGROUND: Interventions with the potential for broad reach in ambulatory settings are necessary to achieve a life course approach to advance care planning. OBJECTIVE: To examine the effect of a computer-tailored, behavioral health model-based intervention on the engagement of adults in advance care planning recruited from ambulatory care settings. DESIGN: Cluster randomized controlled trial with participant-level analysis. (ClinicalTrials.gov: NCT03137459). SETTING: 10 pairs of primary and selected specialty care practices matched on patient sociodemographic information. PARTICIPANTS: English-speaking adults aged 55 years or older; 454 adults at practices randomly assigned to usual care and 455 at practices randomly assigned to intervention. INTERVENTION: Brief telephone or web-based assessment generating a mailed, individually tailored feedback report with a stage-matched brochure at baseline, 2 months, and 4 months. MEASUREMENTS: The primary outcome was completion of the following 4 advance care planning activities at 6 months: identifying and communicating with a trusted person about views on quality versus quantity of life, assignment of a health care agent, completion of a living will, and ensuring that the documents are in the medical record-assessed by a blinded interviewer. Secondary outcomes were completion of individual advance care planning activities. RESULTS: Participants were 64% women and 76% White. The mean age was 68.3 years (SD, 8.3). The predicted probability of completing all advance care planning activities in usual care sites was 8.2% (95% CI, 4.9% to 11.4%) versus 14.1% (CI, 11.0% to 17.2%) in intervention sites (adjusted risk difference, 5.2 percentage points [CI, 1.6 to 8.8 percentage points]). Prespecified subgroup analysis found no statistically significant interactions between the intervention and age, education, or race. LIMITATIONS: The study was done in a single region and excluded non-English speaking participants. No information was collected about nonparticipants. CONCLUSION: A brief, easily delivered, tailored print intervention increased participation in advance care planning in ambulatory care settings. PRIMARY FUNDING SOURCE: National Institute of Nursing Research and National Institute of Aging.

RESUMEN

OBJECTIVES: Uptake of psychosocial services during cancer treatment remains relatively low. To use these services efficiently, novel approaches - based on evidence-based theory - are needed to understand cancer patients' readiness to seek psychosocial services. Guided by the transtheoretical model (TTM), we investigated individuals' readiness to use psychosocial services by assessing decisional conflict (pros/cons) and self-efficacy, which are established as the most important constructs of predicting a specific behavior. METHODS: In these secondary analyses, we examined demographic and treatment-related factors in a national sample of adult cancer patients and survivors in the United States as predictors of decisional balance (pros/cons) and self-efficacy (i.e., two core TTM constructs) of engaging in psychosocial services. Participants were recruited through an online survey. In addition to examining demographic factors (age, sex, race, and marital status) as independent variables using t tests and correlations, treatment-related variables, such as having multiple cancers, type of cancer, type of treatment, and treatment setting were included. RESULTS: Four hundred and sixty-six participants completed the survey. The sample was primarily Caucasian (79%) and female (54.7%); average age was 47.9 (SD = 14.8). While no significant relationships emerged for self-efficacy, younger age and non-Caucasian race were significantly related to greater cons of seeking psychosocial care. Finally, those with multiple cancers versus reporting only one malignancy endorsed more cons of seeking psychosocial care. CONCLUSIONS: These data highlight the importance of measuring the cons of seeking psychosocial care during cancer treatment, with younger age, non-Caucasian, and those reporting experience with multiple cancers endorsing greater cons. This may impact eventual uptake of available services. Future research should identify individuals at risk for declining services based on perceived cons of seeking psychosocial care during cancer.

RESUMEN

This study assessed impact of Coordinated Specialty Care (CSC), expanded to include both first episode psychosis (FEP) and severe mental health disorders (e.g., depression, bipolar disorder, trauma) in youths attending Community Mental Health Centers (CMHCs). Eligible youth and young adults (ages 16-26 years, N = 201) were recruited from two CMHCs and assessed every 6 months. Paired sample t-tests were performed comparing pre- and post-treatment observations. Statistically significant decreases from pre to post were found in sad and anxious feelings and in days hospitalized for psychiatric emergency and increases were found in subjective health ratings and employment status. This preliminary assessment supports the effectiveness of expanded inclusion criteria for participation in the CSC model.

RESUMEN

Cancer patients frequently experience considerable distress during diagnosis and treatment. The aims of this study were to describe the development and utilization of a psychological service for cancer patients at a community hospital-and to provide preliminary results on clinical outcomes in a "real-world" clinical setting. This program was developed collaboratively by individuals from a university-based clinical psychology doctoral program and a community hospital. The psychological service was comprised of a licensed, PhD-level clinical psychologist and seven clinical psychology doctoral students. Patients were typically referred by their oncologists or nurses. Distress, depression, and anxiety were evaluated for a small subsample of participants. From the time the program was initiated, 238 patients between ages 18 and 95 (M = 66.4) were evaluated over a 3-year period. Most patients (77.8%) were offered psychosocial care. Although 49.8% declined treatment, 23.6% attended one session and 26.6% attended two or more. Average number of individual sessions was 2.77 (SD=8.31, range=0-96) and 0.06 (SD=0.43, range=0-4) for groups sessions. Patients referred through the Survivorship Training and Rehabilitation (STAR) Program® (i.e., a program providing multidisciplinary services) were more likely to engage in psychosocial care than those who found out about behavioral health in other ways. Patients experienced declines in depression (Wilks' Λ=.580, F(2, 14)=5.08, p=.022), but not anxiety (Wilks' Λ=.613, F(2, 12)=3.79, p=.053) across sessions. An in-depth case description is provided. Distress tracking may be improved if nurses, oncologists, and behavioral health providers administer measures. Partnerships between clinical psychology doctoral programs and hospitals may be mutually beneficial - and may advance the dissemination and implementation of evidence-based psychosocial interventions. Hospitals offering cancer treatment may benefit from generating referrals for comprehensive cancer care. These efforts can serve as a model for other hospitals seeking to integrate behavioral health into routine cancer treatment.

RESUMEN

The fourteen-factor Processes of Change Scale for Sun Protection assesses behavioral and experiential strategies that underlie the process of sun protection acquisition and maintenance. Variations of this measure have been used effectively in several randomized sun protection trials, both for evaluation and as a basis for intervention. However, there are no published studies, to date, that evaluate the psychometric properties of the scale. The present study evaluated factorial invariance and scale reliability in a national sample (N = 1360) of adults involved in a Transtheoretical model tailored intervention for exercise and sun protection, at baseline. Invariance testing ranged from least to most restrictive: Configural Invariance (constraints only factor structure and zero loadings); Pattern Identity Invariance (equal factor loadings across target groups); and Strong Factorial Invariance (equal factor loadings and measurement errors). Multi-sample structural equation modeling tested the invariance of the measurement model across seven subgroups: age, education, ethnicity, gender, race, skin tone, and Stage of Change for Sun Protection. Strong factorial invariance was found across all subgroups. Internal consistency coefficient Alpha and factor rho reliability, respectively, were .83 and .80 for behavioral processes, .91 and .89 for experiential processes, and .93 and .91 for the global scale. These results provide strong empirical evidence that the scale is consistent, has internal validity and can be used in research interventions with population-based adult samples.

RESUMEN

The transition from childhood to adolescence is a crucial period for the development of healthy behaviors to be sustained later in life. With obesity a leading public health problem, the promotion of healthy behaviors has the potential to make a huge impact. The current study evaluated Stage of Change progression in a large (N = 4158) computer-delivered, Transtheoretical Model-tailored intervention focusing on physical activity and fruit and vegetable consumption (FV). Markov models were used to explore stage transitions and patterns of discrete change from sixth to ninth grade. Nested model comparisons examined the consistency of these patterns across time and intervention condition. Major findings supported models in which participants were free to transition forward and backward to any of the stages, but higher probabilities were observed for remaining in the same stage or for transitioning one or two stages forward. Participants in the intervention group had higher probabilities of transitioning toward Maintenance, with more change occurring relative to the comparison group during transitions from grades six to eight but not for grades eight to nine.

RESUMEN

The World Health Organization has recommended the scale-up of voluntary medical male circumcision (VMMC) for HIV prevention in sub-Saharan Africa; however, men are often uninterested in undergoing VMMC. The Spear & Shield project enrolled 668 men and female partners from ten Zambian community health centers into parallel interventions promoting VMMC for HIV prevention or time-matched control conditions. A mediation model was utilized to examine the relationships between changes in women's acceptance of VMMC and men's readiness to undergo the procedure. Results demonstrated that, at 12 months post-intervention, a 5.9 % increase in the likelihood of undergoing VMMC among men in the experimental condition could be attributed to increased women's acceptance. From a public health perspective, involving women in VMMC promotion interventions such as the Spear & Shield project could significantly impact the demand for VMMC in Zambia.

RESUMEN

BACKGROUND: Traditional null hypothesis significance testing suffers many limitations and is poorly adapted to theory testing. PURPOSE: A proposed alternative approach, called Testing Theory-based Quantitative Predictions, uses effect size estimates and confidence intervals to directly test predictions based on theory. METHOD: This paper replicates findings from previous smoking studies and extends the approach to diet and sun protection behaviors using baseline data from a Transtheoretical Model behavioral intervention (N = 5407). Effect size predictions were developed using two methods: (1) applying refined effect size estimates from previous smoking research or (2) using predictions developed by an expert panel. RESULTS: Thirteen of 15 predictions were confirmed for smoking. For diet, 7 of 14 predictions were confirmed using smoking predictions and 6 of 16 using expert panel predictions. For sun protection, 3 of 11 predictions were confirmed using smoking predictions and 5 of 19 using expert panel predictions. CONCLUSION: Expert panel predictions and smoking-based predictions poorly predicted effect sizes for diet and sun protection constructs. Future studies should aim to use previous empirical data to generate predictions whenever possible. The best results occur when there have been several iterations of predictions for a behavior, such as with smoking, demonstrating that expected values begin to converge on the population effect size. Overall, the study supports necessity in strengthening and revising theory with empirical data.

RESUMEN

PURPOSE: This research examined dynamic transtheoretical model (TTM) constructs for adopting sun protection practices. This secondary data analysis pooled four large population-based TTM-tailored intervention studies and examined use of constructs across three groups, organized by longitudinal progress: maintainers, relapsers, and stable non-changers. METHODS: A total of 3463 adults, in the USA, who met criteria for unsafe sun exposure at baseline received a TTM-tailored computerized intervention at baseline, 6 months, and 12 months. The final analytic sample consisted of 1894 participants; the majority were female, White, married, and middle-aged. The three groups were assessed with reliable and valid scales assessing use of TTM constructs at baseline, 6 months, 12 months, and 24 months. Analyses included a MANOVA followed by a series of ANOVAs, with Tukey follow-up tests assessing differences in use of TTM constructs across the three groups at each timepoint. RESULTS: Findings demonstrated that relapsers and maintainers were similar in their use of most TTM processes of change at baseline, with the exception of Consciousness Raising, Stimulus Control, Reinforcement Management, and Self-Liberation. CONCLUSIONS: These findings suggest that although relapsers reverted to unsafe sun practices, their overall greater use of processes of change indicates that their change efforts remain better than that of stable non-changers.

RESUMEN

This research examined dynamic transtheoretical model (TTM) constructs for dietary fat reduction. This secondary data analysis pooled three large population-based TTM-tailored school, worksite, medical, and home-based intervention studies and examined use of constructs across three groups organized by longitudinal progress (dynatypes): Maintainers, Relapsers, and Stable Non-Changers. The criteria for successful change, at the time, were that less than 30% of calories came from fat. A total of 2,718 adults met criteria for an unhealthy diet at baseline. The majority of participants were female, White, married, and middle-aged. Demographics, Stage of Change, Processes of Change, Decisional Balance, and Temptations were measured. Dynatype groups were assessed with reliable and valid scales assessing constructs at baseline and 6, 12, and 24 months. Analyses included a multivariate analysis of variance followed by a series of analyses of variance, with Tukey follow-up tests assessing differences in use of TTM constructs across the three groups at each time point. Relapsers and Maintainers were similar in their use of all TTM Processes of Change at baseline, with the exception of Self-Liberation (η(2) = 0.15, p < .001) and Reinforcement Management (η(2) = 0.01, p < .001). Although Relapsers reverted to an unhealthy diet, their overall greater use of Processes of Change suggests that their behaviors and strategy use remain better than that of the Stable Non-Changer group. Results suggest that specific cognitive and behavioral constructs may contribute differentially to intervention outcomes.

RESUMEN

Smoking and sexual risk behaviors in urban adolescent females are prevalent and problematic. Family planning clinics reach those who are at most risk. This randomized effectiveness trial evaluated a transtheoretical model (TTM)-tailored intervention to increase condom use and decrease smoking. At baseline, a total of 828 14- to 17-year-old females were recruited and randomized within four urban family planning clinics. Participants received TTM or standard care (SC) computerized feedback and stage-targeted or SC counseling at baseline, 3, 6 and 9 months. Blinded follow-up telephone surveys were conducted at 12 and 18 months. Analyses revealed significantly more consistent condom use in the TTM compared with the SC group at 6 and 12, but not at 18 months. In baseline consistent condom users (40%), significantly less relapse was found in the TTM compared with the SC group at 6 and 12, but not at 18 months. No significant effects for smoking prevention or cessation were found, although cessation rates matched those found previously. This TTM-tailored intervention demonstrated effectiveness for increasing consistent condom use at 6 and 12 months, but not at 18 months, in urban adolescent females. This intervention, if replicated, could be disseminated to promote consistent condom use and additional health behaviors in youth at risk.

RESUMEN

BACKGROUND: Dissemination and scale up of voluntary medical male circumcision (VMMC) programs is well supported by evidence that VMMC reduces HIV risk in populations with high HIV prevalence and low rates of circumcision, as is the case in Zambia. PURPOSE: At both individual and population levels, it is important to understand what stages of change for VMMC are associated with, especially across cultures. This study evaluated VMMC knowledge, misinformation, and stages of change for VMMC of uncircumcised men and boys (over 18 years), as well as the concurrent relationship between VMMC stages of change and sexual risk behaviors. METHOD: Uncircumcised (N = 800) adult men and boys (over 18) were screened and recruited from urban community health centers in Lusaka, Zambia, where they then completed baseline surveys assessing knowledge, attitudes, HIV risk behaviors, and stages of change for VMMC. A series of analyses explored cross-sectional relationships among these variables. RESULTS: VMMC was culturally acceptable in half of the sample; younger, unmarried, and more educated men were more ready to undergo VMMC. Stage of change for VMMC was also related to knowledge, and those at greater HIV risk reported greater readiness to undergo VMMC. CONCLUSIONS: Efforts to increase VMMC uptake should address the role of perceived HIV risk, risk behaviors, readiness, accurate knowledge, cultural acceptance, and understanding of the significant degree of HIV protection conferred as part of the VMMC decision making process. These results support incorporating comprehensive HIV risk reduction in VMMC promotion programs.

RESUMEN

Single occupancy vehicle (SOV) transportation is a key contributor to climate change and air pollution. Sustainable transportation (ST), commuting by any means other than SOV, could both slow climate change and enhance public health. The transtheoretical model (TTM) provides a useful framework for examining how people progress towards adopting ST. Short valid and reliable measures for ST decisional balance, self-efficacy, and climate change doubt were developed and their relationship with stages of change was examined. Two large university-based volunteer samples participated in measurement studies. Using multiple procedures, three brief internally consistent measures were developed: decisional balance, self-efficacy, and climate change doubt. The stages of change correctly discriminated both decisional balance and self-efficacy, as well as replicated hypothesized relationships. Climate change doubt did not vary by stages; however, it may prove useful in future studies. Results support the validation of these measures and the application of the TTM to ST.

RESUMEN

This study examined longitudinal differences in use of transtheoretical model (TTM) behavior change constructs in maintainers (who reached and maintained exercise guidelines), relapsers (who reached guidelines, then regressed), and nonchangers (who did not reach guidelines). Data from two population-based TTM-tailored randomized trial intervention groups targeting exercise behavior (N = 1050) were pooled, and analyses assessed differences in TTM constructs between the three groups at baseline, 12 months, and 24 months. Findings indicated that relapsers tended to use TTM variables similarly to maintainers with the exception of self-efficacy, consciousness raising, and most behavioral processes of change, at 24 months. Nonchangers, however, used all TTM variables less than maintainers at nearly every time point. Findings suggest that relapsers remain more active than nonchangers in terms of use of change processes. Poor response to interventions (nonchangers) may be predicted by low baseline engagement in change processes. Although relapsers reverted to physical inactivity, their overall greater use of TTM constructs suggests that their efforts to change remain better than those of the stable nonchanger group. Future research can focus on treatment engagement strategies to help the stable nonchangers initiate change and to help relapsers to maintain treatment gains.

RESUMEN

There is limited information about the influence of partners on medical male circumcision (MMC) uptake. This study aimed to evaluate attitudes, knowledge, and preferences about MMC among men and their partners, and their relative impact on male readiness to undergo the MMC procedure. Male participants (n = 354) and their partners (n = 273) were recruited from community health centers in Lusaka, Zambia. Men reported their readiness to undergo MMC, and both men and women were assessed regarding their attitudes and knowledge regarding MMC. Men who had discussed MMC with their partners, those who endorsed MMC for HIV risk reduction, and those viewing MMC as culturally acceptable reported increased readiness to undergo MMC. Additionally, endorsement of MMC by female partners was associated with increased men's readiness. Results support promotion of cultural acceptability of MMC, and efforts to increase MMC uptake may benefit from incorporating partners in the decision making process.

RESUMEN

OBJECTIVE: Predictive and external validity was studied among cluster profiles for sun protection behavior within stages from Transtheoretical Model of behavior change using follow-up data. METHODS: Data from participants in a home-based expert system were analyzed. Longitudinal patterns of clusters on the precontemplation, contemplation, and preparation stages of change were assessed. Differences between clusters on membership in action/maintenance stages and scores on the Sun Protection Behavior Scale (SPBS) were measured at 12 and 24 months after intervention. RESULTS: Differences between clusters on stage progression and on scores from the SPBS were found at 12 and 24 months after intervention at all stages. DISCUSSION: Predictive and external validity of sun protection subtypes was established using sun protection variables after a stage-matched intervention. Results provide information to improve interventions for sun protection.

RESUMEN

OBJECTIVE: This study compared, in treatment and control groups, the phenomena of coaction, which is the probability that taking effective action on one behavior is related to taking effective action on a second behavior. METHODS: Pooled data from three randomized trials of Transtheoretical Model (TTM) tailored interventions (n=9461), completed in the U.S. in 1999, were analyzed to assess coaction in three behavior pairs (diet and sun protection, diet and smoking, and sun protection and smoking). Odds ratios (ORs) compared the likelihood of taking action on a second behavior compared to taking action on only one behavior. RESULTS: Across behavior pairs, at 12 and 24 months, the ORs for the treatment group were greater on an absolute basis than for the control group, with two being significant. The combined ORs at 12 and 24 months, respectively, were 1.63 and 1.85 for treatment and 1.20 and 1.10 for control. CONCLUSIONS: The results of this study with addictive, energy balance and appearance-related behaviors were consistent with results found in three studies applying TTM tailoring to energy balance behaviors. Across studies, there was more coaction within the treatment group. Future research should identify predictors of coaction in more multiple behavior change interventions.

RESUMEN

BACKGROUND: The transtheoretical model is an influential theoretical model in health psychology, particularly in its application to smoking cessation research. Decisional Balance (DB) and Temptations are key constructs within this framework. PURPOSE: This study examines the psychometric properties of the DB and Temptations scales for smoking in a predominantly African-American sample of urban adolescent girls. METHODS: We used confirmatory factor analysis to compare the fit of previously published factor structures in smokers (n = 233) and nonsmokers (n = 598). External validity was tested by examining stages of change differences in the retained subscales. RESULTS: Results supported the internal and external validity of the DB scale for smokers and nonsmokers. Notably, previously published three-factor (Social Pros, Coping Pros, Cons) and four-factor (Cons split into "Aesthetic Cons" and "Health Cons") models fit equally well, with Cons subscales correlating highly. For Temptations, a previously published three-factor (Negative Affect, Social, Weight Control) hierarchical model fit well in nonsmokers. In smokers, previously published subscales were reliably measured, but their structural relationship remained unclear. Stage difference tests showed medium to large effect sizes of DB and Temptation subscales in smokers and nonsmokers. CONCLUSIONS: The use of DB was validated for both smokers and nonsmokers in this sample of primarily African-American adolescent females, where Cons can be combined or separated into "Aesthetic Cons" and "Health Cons" based on practical utility and preference. For Temptations, more research is needed but large stage differences in Temptations subscales underscore the importance of this concept in smoking acquisition and cessation.
