The Stride program: Feasibility and pre-to-post program change of an exercise service for university students experiencing mental distress

Rates of mental illness are disproportionately high for young adult and higher education (e.g., university student) populations. As such, universities and tertiary institutions often devote significant efforts to services and programs that support and treat mental illness and/or mental distress. However, within that portfolio of treatment approaches, structured exercise has been relatively underutilised and greater research attention is needed to develop this evidence base. The Stride program is a structured 12-week exercise service for students experiencing mental distress. We aimed to explore the feasibility of the program and assess pre- and post-program change, through assessments of student health, lifestyle, and wellbeing outcomes. Drawing from feasibility and effectiveness-implementation hybrid design literatures, we conducted a non-randomised feasibility trial of the Stride program. Participants were recruited from the Stride program (N = 114, M_age = 24.21 years). Feasibility results indicated the program was perceived as acceptable and that participants reported positive perceptions of program components, personnel, and sessions. Participants’ pre-to-post program change in depressive symptomatology, physical activity levels, mental health-related quality of life, and various behavioural outcomes were found to be desirable. Our results provide support for the feasibility of the Stride program, and more broadly for the delivery and potential effectiveness of structured exercise programs to support university students experiencing mental distress.     

Is Salesperson Attractiveness a Boon or a Bane? The Moderating Role of Perceived Labor Cost‐To‐Price Ratio in Retail Bargaining

This research examines the important but unexamined effects of salesperson attractiveness on consumer bargaining behavior in retail contexts. In line with our theorizing, three studies demonstrate that the effect of salesperson attractiveness on consumer bargaining depends on their general beliefs regarding the impact of labor costs on retail prices. While consumers bargain less with an attractive salesperson when their labor costs‐to‐price (LP) ratio beliefs are relatively low, they bargain harder with an attractive, as opposed to a less attractive, salesperson, when their LP ratio beliefs are relatively high. As well, we provide evidence for the process, based on the salesperson's perceived trustworthiness and consumers' consequent bargaining stance toward her.     

Daily relations between social perceptions and physical activity among college women

ObjectivesThere is a need to develop more effective physical activity (PA) promotion programs for college women. Theory and evidence suggest that perceptions of the social environment play a role in college women’s PA, though little is known about how these perceptions are associated with PA at the day level. The goal of this study was to examine relations between changes in college women’s daily social perceptions and objectively assessed PA over seven days.DesignDaily diary method.MethodCollege women (n = 80, M_Age = 20, M_BMI = 23.1 kg/m²) wore Fitbit wristbands and completed daily self-reports of (1) the quantity and perceived intensity of their social interactions (positive/negative), and (2) the occurrence of social comparisons (based on appearance/health/status) for seven days.ResultsMultilevel models showed daily variability in predictors and outcomes (ps < 0.0001), as well as relations between within-person changes in social perceptions and PA. Increases in negative interactions (particularly those with friends) were consistently associated with decreases in daily PA, whereas increases in positive interactions showed limited relations (srs = −0.22-0.34). Days with health comparisons were days with greater PA for women who had stronger overall interest in comparisons, but were days with less PA for women with weaker overall interest (srs = 0.22–0.33). PA did not differ between days with vs. without appearance comparisons.ConclusionsSocial perceptions show meaningful day-to-day variability and relations with college women’s daily PA, and specific associations may be useful for improving tailored interventions for college women.     

Within-day time-varying associations between motivation and movement-related behaviors in older adults

ObjectivesEmerging evidence suggests both motivation and movement-related behaviors vary within and across days. Yet common data analytic approaches assume static or consistent relationships between motivation and behavior across time. Just as motivation and behavior change across time, so too might associations between motivation and behavior. This study will apply time-varying effect modeling to Ecological Momentary Assessment (EMA) data to examine time of day differences in how motivational constructs predict older adults’ subsequent movement-related behavior over the next 2 h.DesignOlder adults (n = 104) completed a 10-day EMA protocol.MethodParticipants answered up to 6 EMA prompts/day to assess momentary intentions and self-efficacy to stand or move as well as intentions and self-efficacy to limit sedentary time over the next 2 h. Participants wore an activPAL accelerometer continuously to measure time spent being upright (i.e., standing or moving) and time spent sitting.ResultsOn weekdays, intentions and self-efficacy were generally predictive of subsequent behavior in the expected direction over the majority of the day whereas these constructs predicted subsequent behavior in the expected directions over a smaller range of times on weekend days.ConclusionsThis study adds to emerging evidence that associations between motivational constructs and subsequent behavior change over the course of the day, but these time-varying associations may be different depending on the day of week. This work has implications for intervention design and the timing of intervention content delivery in approaches like just-in-time adaptive interventions.     

Longitudinal relations between psychological distress and moderate-to-vigorous physical activity: A latent change score approach

ObjectivesThe effect of physical inactivity on mental health risk is well established; however, less is known about about how psychological distress might deter participation in physical activity. Guided by advancements in the treatment of longitudinal data, the aim of this study was to examine patterns and predictors of change in moderate-to-vigorous physical activity (MVPA) and psychological distress (e.g., feeling nervous, worthless).Design methodAustralian adults (4944 females, M_age = 34.63 years ±5.34; 4322 males, M_age = 37.51 years ±6.14) provided baseline data as part of the Longitudinal Study of Australian Children (LSAC) and were followed for measurements every two years for 10 years.ResultsLatent change score analyses revealed support for a reciprocal effects model, whereby change in MVPA and psychological distress occurred as a function of individuals’ prior levels of, and/or prior change in these variables.ConclusionsThis investigation is the first to document that changes in MVPA and psychological distress are coupled temporally. Notably, we observed that individuals’ distress levels at a given time point predicted subsequent change on both MVPA and distress; a finding which provides novel and important insight into how adults’ activity levels and psychological distress fluctuate relative to one another.     

Experimental comparison of physical activity self-efficacy measurement: Do vignettes reduce motivational confounding?

ObjectivesSelf-efficacy is one of the most reliable correlates of physical activity, yet a growing body of literature has demonstrated that traditional self-efficacy measures may be flawed because they measure perceived capability and other constructs such as motivation. This study adds to this evidence base by comparing a standard self-efficacy measurement group and two measurement conditions that may provide greater validity: motivation held constant (i.e., adding “If you really wanted to” at the beginning of the item) and vignette (i.e., adding a clarifying vignette before the item). The first objective of this study was to compare these groups regarding self-efficacy scores. The second objective was to examine whether physical activity level (i.e., adhering to physical activity guidelines or not) interacted with measurement condition.DesignRandomized cross-sectional design with three independent groups.MethodParticipants were 444 undergraduate students (M age in years = 21.10, SD = 3.73) who completed an online survey measuring physical activity self-efficacy and behaviour.ResultsThe vignette group had higher self-efficacy scores than the standard and motivation held constant groups. Scores were also higher among those adhering to guidelines and there were no differences between the groups for physically active individuals. Finally, among those not adhering to the guidelines, the vignette group had especially high scores compared to the other groups.ConclusionsThis study demonstrated that reading a vignette prior to completing a self-efficacy item clarifies the meaning of the item thereby improving validity of the measure.     

Unattractive people are unaware of their (un)attractiveness

Past research has shown that how people rate their physical attractiveness is only moderately correlated with how they are rated by others, suggesting that at least some people have little insight into their true level of attractiveness. The present research tests the hypothesis that unattractive people are not aware of their unattractiveness. In fact, six studies (overall N = 1,180) showed that unattractive participants considerably overestimated their attractiveness compared to ratings by strangers. In contrast, attractive participants were more accurate. If anything, they underestimated their attractiveness. It was also examined why unattractive people overestimate their attractiveness. As expected, unattractive participants differentiated less between attractive and unattractive stimulus persons than did attractive participants. They were also more likely than attractive participants to select unattractive stimulus persons to compare themselves to. However, these tendencies did not account for why unattractive participants overestimated their attractiveness, nor did affirming participant’s self-worth. Limitations and avenues for future research are discussed.     

Violence against women: Mental health effects. Part II. Conceptualizations of posttraumatic stress

A broad range of psychological aftereffects have been noted among women who have experienced male-perpetrated violence. These symptoms vary considerably among individuals, across social contexts, and across different types of violent encounters (Coley & Beckett, 1988; Goodman, Koss, & Russo, 1992; Koss, 1988; Straus, Gelles, & Steinmetz, 1980). Nevertheless, a remarkably consistent picture of the psychological sequelae of violence—particularly sexual and physical assault—emerges from the empirical and clinical literature (Koss, 1988). In this article, we use the posttraumatic stress disorder diagnosis—a frame that captures many of the disparate symptoms described by researchers—as a basis for exploring several conceptual models that have been developed to explain women's responses to violence.     

Neurocognitive Effects of Methamphetamine: A Critical Review and Meta-analysis

This review provides a critical analysis of the central nervous system effects of acute and chronic methamphetamine (MA) use, which is linked to numerous adverse psychosocial, neuropsychiatric, and medical problems. A meta-analysis of the neuropsychological effects of MA abuse/dependence revealed broadly medium effect sizes, showing deficits in episodic memory, executive functions, information processing speed, motor skills, language, and visuoconstructional abilities. The neuropsychological deficits associated with MA abuse/dependence are interpreted with regard to their possible neural mechanisms, most notably MA-associated frontostriatal neurotoxicity. In addition, potential explanatory factors are considered, including demographics (e.g., gender), MA use characteristics (e.g., duration of abstinence), and the influence of common psychiatric (e.g., other substance-related disorders) and neuromedical (e.g., HIV infection) comorbidities. Finally, these findings are discussed with respect to their potential contribution to the clinical management of persons with MA abuse/dependence.     

Stacking of blocks by chimpanzees: developmental processes and physical understanding

The stacking-block task has been used to assess cognitive development in both humans and chimpanzees. The present study reports three aspects of stacking behavior in chimpanzees: spontaneous development, acquisition process following training, and physical understanding assessed through a cylindrical-block task. Over 3 years of longitudinal observation of block manipulation, one of three infant chimpanzees spontaneously started to stack up cubic blocks at the age of 2 years and 7 months. The other two infants began stacking up blocks at 3 years and 1 month, although only after the introduction of training by a human tester who rewarded stacking behavior. Cylindrical blocks were then introduced to assess physical understanding in object-object combinations in three infant (aged 3-4) and three adult chimpanzees. The flat surfaces of cylinders are suitable for stacking, while the rounded surface is not. Block manipulation was described using sequential codes and analyzed focusing on failure, cause, and solution in the task. Three of the six subjects (one infant and two adults) stacked up cylindrical blocks efficiently: frequently changing the cylinders' orientation without contacting the round side to other blocks. Rich experience in stacking cubes may facilitate subjects' stacking of novel, cylindrical shapes from the beginning. The other three subjects were less efficient in stacking cylinders and used variable strategies to achieve the goal. Nevertheless, they began to learn the effective way of stacking over the course of testing, after about 15 sessions (75 trials).
