RESUMO

Social ecological and developmental system perspectives suggest that interactions among factors within and across multiple contexts (e.g., neighborhood, peer, family) must be considered in explaining dating violence perpetration. Yet, to date, most extant research on dating violence has focused on individual, rather than contextual predictors, and used variable-centered approaches that fail to capture the configurations of factors that may jointly explain involvement in dating violence. The current study used a person-centered approach, latent profile analysis, to identify key configurations (or profiles) of contextual risk and protective factors for dating violence perpetration across the neighborhood, school, friend and family contexts. We then examine the longitudinal associations between these contextual risk profiles, assessed during middle school, and trajectories of psychological and physical dating violence perpetration across grades 8 through 12. Five contextual risk profiles were identified: school, neighborhood, and family risk; school and family risk; school and friend risk; school and neighborhood risk; and low risk. The highest levels of psychological and physical perpetration across grades 8 through 12 were among adolescents in the profile characterized by high levels of school, neighborhood, and family risk. Results suggest that early interventions to reduce violence exposure and increase social regulation across multiple social contexts may be effective in reducing dating violence perpetration across adolescence.

RESUMO

Male perpetration of intimate partner violence (IPV) against women in sub-Saharan Africa is widespread. Theory and empirical evidence suggest peer networks may play an important role in shaping IPV perpetration, though research on this topic in the region is limited. We assessed the degree to which peer network gender norms are associated with Tanzanian men's perpetration of IPV and examined whether the social cohesion of peer networks moderates this relationship. Using baseline data from sexually active men (n = 1103) nested within 59 peer networks enrolled in an on-going cluster-randomized HIV and IPV prevention trial, we fit multilevel logistic regression models to examine peer network-level factors associated with past-year physical IPV perpetration. Peer network gender norms were significantly associated with men's risk of perpetrating IPV, even after adjusting for their own attitudes toward gender roles (OR = 1.53 , p = . 04). Peer network social cohesion moderated this relationship (OR = 1.50 , p = . 04); the positive relationship between increasingly inequitable (i.e., traditional) peer network gender norms and men's risk of perpetrating IPV became stronger, as peer network social cohesion increased. Characteristics of the peer network context are associated with men's IPV perpetration and should be targeted in future interventions. While many IPV prevention interventions focus on changing individual attitudes, our findings support a unique approach, focused on transforming the peer context.

RESUMO

Theory and research suggest that there may be significant heterogeneity in the development, manifestation, and consequences of adolescent dating violence that is not yet well understood. The current study contributed to our understanding of this heterogeneity by identifying distinct patterns of involvement in psychological, physical, and sexual dating violence victimization and perpetration in a sample of Latino youth (n = 201; M = 13.87 years; 42% male), a group that is understudied, growing, and at high risk for involvement in dating violence. Among both boys and girls, latent class analyses identified a three-class solution wherein the largest class demonstrated a low probability of involvement in dating violence across all indices ("uninvolved"; 56% of boys, 64% of girls) and the smallest class demonstrated high probability of involvement in all forms of dating violence except for sexual perpetration among girls and physical perpetration among boys ("multiform aggressive victims"; 10% of boys, 11% of girls). A third class of "psychologically aggressive victims" was identified for which there was a high probability of engaging and experiencing psychological dating violence, but low likelihood of involvement in physical or sexual dating violence (34% of boys, 24% of girls). Cultural (parent acculturation, acculturation conflict), family (conflict and cohesion) and individual (normative beliefs, conflict resolution skills, self-control) risk and protective factors were associated with class membership. Membership in the multiform vs. the uninvolved class was concurrently associated with emotional distress among girls and predicted emotional distress longitudinally among boys. The results contribute to understanding heterogeneity in patterns of involvement in dating violence among Latino youth that may reflect distinct etiological processes.

RESUMO

Moms and Teens for Safe Dates (MTSD) is a dating abuse (DA) prevention program for teens exposed to domestic violence. In a randomized controlled trial (RCT), MTSD prevented certain types of DA victimization (psychological and physical) and perpetration (psychological and cyber) among teens with higher, but not lower, exposure to domestic violence. We built on these findings by using moderated mediation analysis to examine whether level of teen exposure to domestic violence conditioned the indirect effects of MTSD on these types of DA through targeted mediators. MTSD consisted of six mailed activity booklets. Mothers who had been former victims of domestic violence delivered the program to their teens. Mother and teen pairs were recruited into the RCT through community advertising and completed baseline and 6-month follow-up interviews (N = 277 pairs). As expected, MTSD had significant favorable effects for teens with higher but not lower exposure to domestic violence on several mediators that guided program content, including teen conflict management skills and mother-perceived severity of DA, self-efficacy for enacting DA prevention efforts, and comfort in communicating with her teen. MTSD had significant main effects on other mediators including teen feeling of family closeness and cohesion and mother-perceived susceptibility of her teen to DA. As expected, all significant indirect effects of MTSD on DA outcomes through mediators were for teens with higher exposure to domestic violence. Findings have implications for developing DA victimization and perpetration prevention programs for teens with high exposure to domestic violence.

RESUMO

This short-term longitudinal study examined whether the association between bullying perpetration and later physical dating violence perpetration and mediators of that association (via anger, depression, anxiety, and social status), varied depending on level of bullying victimization. Differences have been noted between those who bully but are not victims of bullying, and those who are both bullies and victims. These differences may influence dating violence risk and the explanations for why bullying leads to dating violence. Data were from dating adolescents in three rural counties who completed self-administered questionnaires in the fall semester of grades 8-10 and again in the spring semester. The sample (N = 2,414) was 44.08% male and 61.31% white. Bullying perpetration in the fall semester predicted physical dating violence perpetration in the spring semester when there was no bullying victimization, but not when there was any bullying victimization. Bullying perpetration was positively associated with anger at all levels of bullying victimization and with social status when there was no or low amounts of victimization; it was negatively associated with social status at high levels of victimization. Bullying victimization was positively associated with anger, depression, and anxiety at all levels of bullying perpetration. Anger mediated the association between bullying perpetration and dating violence, regardless of level of victimization; depression, anxiety, and social status did not mediate the association at any level of bullying victimization. The findings have implications for dating violence prevention efforts and for future research on the link between bullying and dating violence.

RESUMO

Commonly used dating violence prevention programs assume that promotion of more egalitarian gender role attitudes will prevent dating violence perpetration. Empirical research examining this assumption, however, is limited and inconsistent. The current study examined the longitudinal association between gender role attitudes and physical dating violence perpetration among adolescent boys (n = 577; 14 % Black, 5 % other race/ethnicity) and examined whether injunctive (i.e., acceptance of dating violence) and descriptive (i.e., beliefs about dating violence prevalence) normative beliefs moderated the association. As expected, the findings suggest that traditional gender role attitudes at T1 were associated with increased risk for dating violence perpetration 18 months later (T2) among boys who reported high, but not low, acceptance of dating violence (injunctive normative beliefs) at T1. Descriptive norms did not moderate the effect of gender role attitudes on dating violence perpetration. The results suggest that injunctive norms and gender role attitudes work synergistically to increase risk for dating violence perpetration among boys; as such, simultaneously targeting both of these constructs may be an effective prevention approach.

RESUMO

The high risk of perpetrating physical dating violence, bullying, and sexual harassment by adolescents exposed to domestic violence points to the need for programs to prevent these types of aggression among this group. This study of adolescents exposed to domestic violence examined whether these forms of aggression share risk factors that could be targeted for change in single programs designed to prevent all three types of aggression. Analyses were conducted on 399 mother victims of domestic violence and their adolescents, recruited through community advertising. The adolescents ranged in age from 12 to 16 years; 64 % were female. Generalized estimating equations was used to control for the covariation among the aggression types when testing for shared risk factors. Approximately 70 % of the adolescents reported perpetrating at least one of the three forms of aggression. In models examining one risk factor at a time, but controlling for demographics, adolescent acceptance of sexual violence, mother-adolescent discord, family conflict, low maternal monitoring, low mother-adolescent closeness, low family cohesion, depressed affect, feelings of anger, and anger reactivity were shared across all three aggression types. In multivariable models, which included all of the risk factors examined and the demographic variables, low maternal monitoring, depressed affect and anger reactivity remained significant shared risk factors. Our findings suggest that programs targeting these risk factors for change have the potential to prevent all three forms of aggression. In multivariable models, poor conflict management skills was a risk for bullying and sexual harassment, but not dating violence; acceptance of dating violence was a risk for dating violence and bullying, but not sexual harassment; and none of the examined risk factors were unique to aggression type. The study's implications for the development of interventions and future research are discussed.

RESUMO

Genetic differences between populations are potentially an important contributor to health disparities around the globe. As differences in gene frequencies influence study design, it is important to have a thorough understanding of the natural variation of the genetic variant(s) of interest. Along these lines, we characterized the variation of the 5HTTLPR and rs25531 polymorphisms in six samples from North America, Southeast Asia, and Africa (Cameroon) that differ in their racial and ethnic composition. Allele and genotype frequencies were determined for 24,066 participants. Results indicated higher frequencies of the rs25531 G-allele among Black and African populations as compared with White, Hispanic and Asian populations. Further, we observed a greater number of 'extra-long' ('XL') 5HTTLPR alleles than have previously been reported. Extra-long alleles occurred almost entirely among Asian, Black and Non-White Hispanic populations as compared with White and Native American populations where they were completely absent. Lastly, when considered jointly, we observed between sample differences in the genotype frequencies within racial and ethnic populations. Taken together, these data underscore the importance of characterizing the L-G allele to avoid misclassification of participants by genotype and for further studies of the impact XL alleles may have on the transcriptional efficiency of SLC6A4.

RESUMO

This study had two objectives: first, to determine the degree to which experiences of victimization by peers during adolescence led to a subsequent rise in depressive symptoms, and second, to identify genetic markers that predict depressive reactivity to victimization. We used a cohort sequential design to obtain a longitudinal sample of 1,475 adolescents (3,263 observations) in Grades 8 to 12 (56% female; 47% Black, 46% White). Multilevel growth curve models were used to assess whether victimization predicted depressive symptoms 6 months later, beyond baseline trajectories for depressive symptoms. We modeled the interactive effects of peer victimization with three genetic polymorphisms (on 5-HTTLPR, DRD2 TaqIA, and BDNF Val66Met) on depressive symptoms. Although victimization predicted subsequent depressive symptoms, there was substantial heterogeneity in the magnitude of the effect of victimization. Val alleles, associated with higher brain-derived neurotrophic factor (BDNF) functioning, predicted more sensitivity to victimization. Neither DRD2 TaqIA, a marker associated with dopaminergic functioning, nor 5-HTTLPR, a marker associated with serotonin activity, was associated with sensitivity to victimization. The social stress of peer victimization triggers depressive symptoms most strongly in individuals who are homozygous for the Val allele on the BDNF Val/Met polymorphism. This polymorphism has been linked with sensitivity to social defeat in animal models. Future research should explore behavioral, cognitive, and emotional explanations of the effects of BDNF Val/Met on responsivity to victimization.

RESUMO

Studies report that alcohol use is related to partner violence, but for many, alcohol use does not culminate in violence against partners. Guided by a self-regulatory failure framework, we predicted that alcohol use would be more strongly associated with dating violence perpetration among adolescents with genotypes linked to impulsivity and emotional reactivity. The hypothesis was tested using random coefficient modeling of data from a multi-wave longitudinal study spanning grades 8-12 (ages 13-18) (n = 1,475). Analyses adjusted for multiple testing and race, and the potential for gene by environment correlation was examined. As predicted, alcohol use was more strongly associated with dating violence among adolescents who had a high rather than a low multilocus genetic profile composed of five genetic markers that influence dopamine signaling. Alcohol use was more strongly related to dating violence among boys with long rather than short 5-HTTLPR alleles, the opposite of the prediction. MAOA-uVNTR did not interact with alcohol, but it had a main effect on dating violence by boys in later grades in the expected direction: boys with more low activity alleles perpetrated more dating violence. Exploratory analyses found variation in findings by race. Our findings demonstrate the importance of incorporating genes into etiological studies of adolescent dating violence, which to date has not been done. Aggr. Behav. Aggr.

RESUMO

Theoretical and empirical evidence suggests that stressful life events are associated with the perpetration of intimate partner violence among adults, but little attention has been given to the relationship between stressful life events and adolescent dating abuse, a prevalent form of violence that results in serious and long-lasting consequences. The current study addresses this gap by examining associations between family-, peer-, school-, and health-related stressful life events and the perpetration of both psychological and physical forms of dating abuse in a sample of 1,125 adolescents (54.6% female, 18% Black), and determining whether these associations are moderated by attributes of the family (closeness to parent) and the adolescent (sex and self-esteem). The total number of stressful events and school-related events were positively associated with the perpetration of psychological dating abuse and family-related events were related to the perpetration of psychological dating abuse for boys, but not girls. Closeness to parent buffered the effect of stressful health-related events on the perpetration of physical dating abuse, but exacerbated the effect of stressful family-related events on the perpetration of physical dating abuse. Health-related events were associated with physical perpetration for those with high, but not low self-esteem. Finally, the total number of stressful events and family-related events were related to the perpetration of physical dating abuse by boys, but not by girls. Taken together, these findings suggest that stressful life events play an important role in adolescent dating abuse, and should be taken into consideration when developing adolescent dating abuse prevention programs.

RESUMO

Neighborhood context plays a role in the development of adolescent health risk behaviors, but few studies have investigated the influence of neighborhoods on the perpetration of dating violence. This longitudinal study examined the direct effects of risky neighborhood structural and physical characteristics on trajectories of the perpetration of dating violence, tested whether collective efficacy mediated these relationships, and determined if the effects varied by the sex of the adolescent. Adolescent data are from a multi-wave longitudinal study from grades 8 to 12; neighborhood data were collected from parents' interviews and U.S. Census data. Multilevel growth curve models were conducted with 3,218 students; the sample was 50% male, 41% White, 50% Black, and 9% other race/ethnicity. In models examining risky neighborhood variables one at a time, and controlling for potential individual-level confounders, the sex of the adolescent interacted with economic disadvantage, residential instability, and physical disorder; these risky neighborhood characteristics increased risk for girls' but not boys' perpetrating of dating violence. In full models with all of the risky neighborhood variables, the sex of the adolescent continued to interact with neighborhood economic disadvantage; living in economically disadvantaged neighborhoods increased girls' but not boys' risk for dating violence across all ages. No other risky neighborhood effects were found for boys or girls. Collective efficacy did not mediate the relationships between other neighborhood characteristics and the outcome. These findings suggest that dating violence prevention strategies for girls should consider the contexts in which they live rather than only targeting changes in their individual characteristics.

RESUMO

Adolescents exposed to domestic violence are at high risk for dating abuse. This randomized controlled trial evaluated a dating abuse prevention program designed specifically for this risk group. Moms and Teens for Safe Dates consisted of six mailed booklets of dating abuse prevention information and interactive activities. Mothers who had been victims of domestic violence but no longer lived with the abuser delivered the program to their adolescents who had been exposed to the abuse. Mother and adolescent pairs (N = 409) were recruited through community advertising; the adolescents ranged from 12 to 16 years old and 64 % were female. Mothers and adolescents completed baseline and 6-month follow-up telephone interviews. Booklet completion in the treatment group ranged from 80 % for the first to 62 % for the last booklet. The analyses first tested whether program effects on dating abuse varied by four a priori identified moderators (mother's psychological health, the amount of adolescent exposure to domestic violence, and adolescent sex and race/ethnicity). Main effects of the program were examined when there were no differential program effects. Program effects on psychological and physical victimization and psychological and cyber perpetration were moderated by the amount of adolescent exposure to domestic violence; there were significant favorable program effects for adolescents with higher, but not lower levels of exposure to domestic violence. There were no moderated or main effects on sexual violence victimization and perpetration or cyber victimization. The findings suggest that a dating abuse prevention program designed for adolescents exposed to domestic violence can have important positive effects.

RESUMO

In response to recent calls for programs that can prevent multiple types of youth violence, the current study examined whether Safe Dates, an evidence-based dating violence prevention program, was effective in preventing other forms of youth violence. Using data from the original Safe Dates randomized controlled trial, this study examined (1) the effectiveness of Safe Dates in preventing peer violence victimization and perpetration and school weapon carrying 1 year after the intervention phase was completed and (2) moderation of program effects by the sex or race/ethnicity of the adolescent. Ninety percent (n = 1,690) of the eighth and ninth graders who completed baseline questionnaires completed the 1-year follow-up assessment. The sample was 51 % female and 26 % minority (of whom 69 % was black and 31 % was of another minority race/ethnicity). There were no baseline treatment group differences in violence outcomes. Treatment condition was significantly associated with peer violence victimization and school weapon carrying at follow-up; there was 12 % less victimization and 31 % less weapon carrying among those exposed to Safe Dates than those among controls. Treatment condition was significantly associated with perpetration among the minority but not among white adolescents; there was 23 % less violence perpetration among minority adolescents exposed to Safe Dates than that among controls. The observed effect sizes were comparable with those of other universal school-based youth violence prevention programs. Implementing Safe Dates may be an efficient way of preventing multiple types of youth violence.

RESUMO

Although numerous studies have established a link between substance use and adult partner violence, little research has examined the relationship during adolescence and most extant research has not examined multiple substance use types. The current study used hierarchical growth modeling to simultaneously examine proximal (between-person) and time-varying (within-person) relations between cigarette, alcohol, marijuana and hard drug use and physical dating aggression across grades 8 through 12 while controlling for demographic covariates and shared risk factors. Proximal effects of marijuana use on dating aggression were found for girls and proximal effects of hard drug use on dating aggression were found for boys. Time-varying effects were found for alcohol for both boys and girls and for hard drug use for boys only. Overall, findings suggest that alcohol, marijuana and hard drug use predict whether and when adolescents engage in dating aggression and should be targeted by prevention interventions.

RESUMO

This study identified classes of developmental trajectories of physical dating violence victimization from grades 8 to 12 and examined theoretically-based risk factors that distinguished among trajectory classes. Data were from a multi-wave longitudinal study spanning 8th through 12th grade (n = 2,566; 51.9 % female). Growth mixture models were used to identify trajectory classes of physical dating violence victimization separately for girls and boys. Logistic and multinomial logistic regressions were used to identify situational and target vulnerability factors associated with the trajectory classes. For girls, three trajectory classes were identified: a low/non-involved class; a moderate class where victimization increased slightly until the 10th grade and then decreased through the 12th grade; and a high class where victimization started at a higher level in the 8th grade, increased substantially until the 10th grade, and then decreased until the 12th grade. For males, two classes were identified: a low/non-involved class, and a victimized class where victimization increased slightly until the 9th grade, decreased until the 11th grade, and then increased again through the 12th grade. In bivariate analyses, almost all of the situational and target vulnerability risk factors distinguished the victimization classes from the non-involved classes. However, when all risk factors and control variables were in the model, alcohol use (a situational vulnerability) was the only factor that distinguished membership in the moderate trajectory class from the non-involved class for girls; anxiety and being victimized by peers (target vulnerability factors) were the factors that distinguished the high from the non-involved classes for the girls; and victimization by peers was the only factor distinguishing the victimized from the non-involved class for boys. These findings contribute to our understanding of the heterogeneity in physical dating violence victimization during adolescence and the malleable risk factors associated with each trajectory class for boys and girls.

RESUMO

Investigators have identified a number of factors that increase risk for physical and psychological dating abuse perpetration during adolescence, but as yet little is known about the etiology of sexual dating aggression during this critical developmental period. This is an important gap in the literature given that research suggests that patterns of sexual dating violence that are established during this period may carry over into young adulthood. Using a sample of 459 male adolescents (76 % White, 19 % Black), the current study used survival analysis to examine the timing and predictors of sexual dating aggression perpetration onset across grades 8 through 12. Risk for sexual dating aggression onset increased across early adolescence, peaked in the 10th grade, and desisted thereafter. As predicted based on the Confluence Model of sexual aggression, associations between early physical aggression towards peers and dates and sexual aggression onset were stronger for teens reporting higher levels of rape myth acceptance. Contrary to predictions, inter-parental violence, prior victimization experiences, and parental monitoring knowledge did not predict sexual dating aggression onset. Findings support the notion that risk factors may work synergistically to predict sexual dating aggression and highlight the importance of rape myth acceptance as a construct that should be addressed by violence prevention programs.

RESUMO

Adolescents develop within multiple contexts that synergistically influence their behavior and health. To understand the simultaneous influence of neighborhood and family contexts on adolescents, this study examined relationships of neighborhood socioeconomic disadvantage, neighborhood social disorganization, family conflict, parent-child bonding and parental control with trajectories of physical and social aggression. The sample included 5,118 adolescents between ages 11 and 18 (50% female, 52% Caucasian) living in predominantly rural areas. Multilevel growth curve models showed an interaction between neighborhood disadvantage, family conflict and gender on the physical aggression trajectories. The interaction suggested more rapid processes of both increase in and desistance from physical aggression over time for boys with high neighborhood disadvantage and high family conflict, as well as a higher starting point, more gradual increase and slower process of desistance over time for girls in similar neighborhood and family contexts. Less parent-child bonding and less parental control also were associated with higher initial levels of physical aggression. For social aggression, an interaction between family conflict and gender showed girls with high family conflict had the highest initial levels of social aggression, with a more gradual increase over time for these girls compared to their male counterparts in high-conflict families or their female counterparts in low-conflict families. Less parent-child bonding was associated with higher initial levels and a faster increase over time of social aggression, and less parental control was associated with higher initial levels of social aggression. The findings suggest early family-based interventions may help prevent perpetration of both physical and social aggression during adolescence.

RESUMO

The peer context is a central focus in research on adolescent risk behaviors but few studies have investigated the role of the peer context in the perpetration of adolescent dating violence. This longitudinal study examined between-subjects and within-person contemporaneous and lagged effects of peer attributes, measured with social network analyses, on trajectories of dating violence perpetration and determined if effects varied by grade and/or sex of the adolescent. Data are from adolescents who participated in a five-wave panel study beginning when they were in 7 through 9th grade and ending when they were in 10 through 12th grade (n = 3,412); half were male, 40.5 % were white, 49.9 % were black and 10.4 % were of another race/ethnicity. Significant between-subjects effects indicate that adolescents who typically have friends who use dating violence, and girls who are typically high in social status, are at increased risk for using dating violence throughout adolescence. Adolescents who typically have high quality friendships and girls who typically have friends with pro-social beliefs are at decreased risk for using dating violence throughout adolescence. Significant within-person contemporaneous effects indicate that both boys and girls reported lower levels of dating violence than usual at times when they had more friends with pro-social beliefs, and reported higher levels of dating violence than usual at times when they had higher social status. None of the lagged effects were significant and none of the effects varied across grade. These findings suggest that the peer context plays an important role in the development of the perpetration of adolescent dating violence.

RESUMO

BACKGROUND: Numerous studies have demonstrated that exposure to caregiver intimate partner violence (IPV) can have cascading negative impacts on children that elevate the risk of involvement in dating abuse. This cascade may be prevented by programs that support the development of healthy relationships in children exposed to IPV. This paper describes the results of a study of the web-based adaptation of an evidence-based dating abuse prevention program for IPV-exposed youth and their maternal caregivers. Core information and activities from an evidence-based program, Moms and Teens for Safe Dates, were adapted to create the web-based program (e-MTSD), which comprises 1 module for mothers only and 5 modules for mother-adolescent dyads to complete together. OBJECTIVE: The primary objective of this study was to evaluate the feasibility and acceptability of the e-MTSD program and the associated research processes. We also examined the practicability of randomizing mothers to receive SMS text message reminders and an action planning worksheet, which were intended to support engagement in the program. METHODS: Mothers were recruited through community organizations and social media advertising and were eligible to participate if they had at least one adolescent aged 12 to 16 years of any gender identity who was willing to participate in the program with them, had experienced IPV after their adolescent was born, and were not currently living with an abusive partner. All mothers were asked to complete the program with their adolescent over a 6- to 8-week period. Participants were randomized to receive SMS text message reminders, action planning, or both using a 2×2 factorial design. Research feasibility was assessed by tracking recruitment, randomization, enrollment, and attrition rates. Program feasibility was assessed by tracking program uptake, completion, duration, and technical problems, and acceptability was assessed using web-based surveys. RESULTS: Over a 6-month recruitment period, 101 eligible mother-adolescent dyads were enrolled in the study and were eligible for follow-up. The median age of the adolescent participants was 14 years; 57.4% (58/101) identified as female, 32.7% (33/101) identified as male, and 9.9% (10/101) identified as gender diverse. All but one mother accessed the program website at least once; 87.1% (88/101) completed at least one mother-adolescent program module, and 74.3% (75/101) completed all 6 program modules. Both mothers and adolescents found the program to be highly acceptable; across all program modules, over 90% of mothers and over 80% of adolescents reported that the modules kept their attention, were enjoyable, were easy to do, and provided useful information. CONCLUSIONS: Findings suggest the feasibility of web-based delivery and evaluation of the e-MTSD program. Furthermore, average ratings of program acceptability were high. Future research is needed to assess program efficacy and identify the predictors and outcomes of program engagement.
