Sexual health education for behavior change: How much is enough?

Purpose: Successful implementation of sexual health curricula in school settings is often compromised by competing academic priorities. This study explores the association between exposure to sexual health lessons (time-on-task in hours and lesson content topics) and delayed sexual initiation of middle school students at long term follow-up. Methods: Post hoc data analysis was conducted from a RCT (n=15 middle schools) in the south-central U.S. in which grade 7 students demonstrated delayed sexual initiation (adjusted odds ratio [AOR]: 1.54, 95% CI: 1.20 to 1.99) by grade 9 follow-up after using It’s Your Game (IYG), a 24 lesson sexual health curriculum. Logistic regression was conducted on a sub-sample of 314 grade 7 and 8 students who received IYG and who were sexually inexperienced at baseline, adjusting for covariates of age, gender, and race/ethnicity to address the impact of lesson exposure variables (time-on-task in hours and type of sexual health content) on initiation of any sex by grade 9. Results: The greatest impact of exposure on delayed sexual initiation was a duration of 13 or more lesson hours (OR = 8.40; p\u3c0.05) and exposure to lesson content on HIV/STI and pregnancy consequences (OR = 4.93; p\u3c0.05). Conclusions: Results support previous exposure studies and provide guidance on how effective sexual health curricula can meet the challenges of delivery in a reduced and competitive academic environment

Machiavellianism, relationship satisfaction, and romantic relationship quality

Machiavellianism is characterised by a manipulative interpersonal style, willingness to exploit others, and a preference for emotionally detached relationships. The present studies investigate the extent to which Machiavellianism influences relationship satisfaction and romantic relationship quality. In study 1, 194 heterosexual partnered women completed Machiavellianism and Relationship Satisfaction measures. Women with higher levels of Machiavellianism reported lower levels of relationship satisfaction. In study 2, 132 heterosexual partnered women completed Machiavellianism, Trust, Commitment, Control, and Emotional Abuse scales. Women with higher levels of Machiavellianism perceived their partners to be less dependable, reported less faith in their partners, and were less willing to persist with the relationship than those with low levels of Machiavellianism. With regards to negative behavior, Machiavellianism predicted each form of control and emotional abuse investigated, such that those with high levels of Machiavellianism were more likely to engage in controlling behaviors and emotional abuse. Findings have important implications for the prediction of romantic relationship quality and in particular for negative behavior such as control and abuse

Native IYG: Improving Psychosocial Protective Factors for HIV/STI and Teen Pregnancy Prevention among Youth in American Indian/Alaska Native Communities

Background: Few HIV/STI and pregnancy prevention programs for youth in American Indian and Alaska Native (AI/AN) communities have been rigorously evaluated despite sexual health disparities in this population. This study reports the evaluation of a culturally adapted Internet-based HIV/STI and pregnancy prevention program for AI/AN youth, Native It’s Your Game (Native IYG). Methods: A randomized study was conducted with 523 youth (12 to 14 years old), recruited from 25 tribal sites in Alaska, Arizona, and the Pacific Northwest. Participants were surveyed at baseline and upon completion of treatment or comparison interventions. Multivariable linear regression models were used to assess impact on short term psychosocial determinants of sexual initiation. Results: A sample of 402 intervention (n=290) and comparison (n=112) youth completed the post-intervention survey (76.9% retention) from 1 to 462 days post-baseline (mean = 114, SD = ±96.67). Participants were 55.5% female, mean age of 13.0 (± 0.97) years with 86.1% self-reporting as AI/AN. Reasons not to have sex, STI knowledge, condom knowledge, condom availability self-efficacy, and condom use self-efficacy were significantly impacted (all P ≤ .01). Limitations included variability in intervention exposure and time between data collection time points. Conclusions: Native IYG demonstrated efficacy to impact short-term psychosocial determinants of sexual behavior in a sample of predominantly AI/AN middle school youth

Comparing Factors Influencing Heavy Episodic Drinking of Young Adults in the United Kingdom and The Netherlands

The United Kingdom and the Netherlands exhibit similar levels of heavy episodic drinking but different drinking patterns among youths. This study aimed to assess the impact of country of residence on heavy episodic drinking among 293 British and Dutch youths, accounting for other behavioral determinants. Participants completed online questionnaires measuring impulsivity, sensation-seeking, alcohol consumption, and constructs from the Theory of Planned Behavior [TPB]. Mediation analysis established that British youths engaged in more frequent heavy drinking episodes than Dutch youths, as they had weaker intentions to refrain from heavy drinking, and lower perceived behavioral control. Country of residence also was a direct predictor of frequency of heavy drinking episodes, not mediated by personality traits. Thus, country of residence seems an important factor in heavy episodic drinking, partly mediated through TPB constructs. Interventions may benefit from targeting country-specific drinking behavior and related socio-psychological mechanisms.</p

Is the media equation a flash in the pan? The durability and longevity of social responses to computers

ABSTRACT Research on social responses to computers often assesses only first-impression reactions during a single experimental session, providing limited knowledge about the lasting effect of the results. In this work, we assess the lasting strength of social desirability bias effects on an interface designed to track exercise, manipulated to have high or low personalization (text vs. anthropomorphic conversational character). After 40 days of daily interactions by 25 participants, we found that self-reported exercise was more accurate when reported to the character vs. text. We also find that, for both conditions, participants&apos; decision to initiate a session is greater when they have done more exercise. Moreover, we show that this effect significantly increases over time for participants in the character condition, and decreases for participants in the text condition. This study demonstrates that Media Equation effects can grow stronger or weaker over time, depending upon the presentation of the interface

Does Survey Format Influence Self-Disclosure on Sensitive Question Items?

Although there are advantages for use of internet based survey research over other formats, there remains in question whether survey mode influences the data measurement equivalency. While most research exploring survey format finds little or no difference in measurement equivalency, the interaction of sensitive topics and survey modality is not fully understood. Additionally, research suggests gender differences in item response on sensitive topics. The present study examined archival data from a college health survey using both online and paper–pencil survey formats. The interaction was evaluated between gender, survey format, and item sensitivity level. Results indicate that question topic sensitivity has a large effect on missing data, and survey format has a moderate effect. These findings have necessary implications for survey design and outcome interpretations

Machiavellianism, emotional manipulation, and friendship functions in women's friendships

Machiavellianism and emotional manipulation has not been investigated in friendships. The current studies investigated Machiavellianism, emotional manipulation, and six friendship functions in women's same-sex friendships. For study 1, women (N = 221) completed the Mach IV, emotional manipulation measure (with reference to their own behaviour and their friend's behaviour), mood worsening and use of inauthentic displays from the managing emotions of others scale, and the friendship function measure. Machiavellianism predicted the self-perceived ability to employ emotional manipulation towards a same-sex friend and perceiving their friend to use emotional manipulation towards them. Machiavellianism predicted lower scores on all six friendship functions. For study 2, women (N = 186) completed the Mach IV, the modified emotional manipulation measure (with reference to their own behaviour and their friend's behaviour), and the friendship function measure. Women high on Machiavellianism reported using emotional manipulation more frequently towards their same-sex friend and perceived their same-sex friend to frequently use emotional manipulation towards them. Machiavellianism predicted lower scores on five of the friendship functions. These studies demonstrated that women higher on Machiavellianism employ emotional manipulation in their same-sex friendships. Women with higher Machiavellianism scores also perceived that they themselves were manipulated by their friend

Peace vision and its socio-emotional antecedents: The role of forgiveness, trust and inclusive victim perceptions

The present study conceptualized peace vision as the view of peace as desirable, feasible and requiring substantial concessions by both parties and examined the social-emotional factors contributing to its endorsement among Israeli Jews (N = 400). In line with our theorizing, we found that trust in Palestinians and inclusive victim perceptions (the view that both conflicting groups have suffered due to the conflict) were significantly and positively associated with peace vision endorsement both directly and indirectly, through facilitating forgiveness. We discuss the theoretical and practical implications of these results in terms of the sustainability of peaceful co-existence between conflicting groups

Neural Activity During Health Messaging Predicts Reductions in Smoking Above and Beyond Self-Report

Objective: The current study tested whether neural activity in response to messages designed to help smokers quit could predict smoking reduction, above and beyond self-report. Design: Using neural activity in an a priori region of interest (a subregion of medial prefrontal cortex [MPFC]), in response to ads designed to help smokers quit smoking, we prospectively predicted reductions in smoking in a community sample of smokers (N = 28) who were attempting to quit smoking. Smoking was assessed via expired carbon monoxide (CO; a biological measure of recent smoking) at baseline and 1 month following exposure to professionally developed quitting ads. Results: A positive relationship was observed between activity in the MPFC region of interest and successful quitting (increased activity in MPFC was associated with a greater decrease in expired CO). The addition of neural activity to a model predicting changes in CO from self-reported intentions, self-efficacy, and ability to relate to the messages significantly improved model fit, doubling the variance explained (R²self-report = .15, R²self-report + neural activity = .35, R²change = .20). Conclusion: Neural activity is a useful complement to existing self-report measures. In this investigation, we extend prior work predicting behavior change based on neural activity in response to persuasive media to an important health domain and discuss potential psychological interpretations of the brain–behavior link. Our results support a novel use of neuroimaging technology for understanding the psychology of behavior change and facilitating health promotion
