Background To track and reduce the spread of COVID-19, apps have been developed to identify contact with individuals infected with SARS-CoV-2 and warn those who are at risk of having contracted the virus. However, the effectiveness of these apps depends highly on their uptake by the general population. Objective The present study investigated factors influencing app use intention, based on the health belief model. In addition, associations with respondents’ level of news consumption and their health condition were investigated. Methods A survey was administered in Flanders, Belgium, to 1500 respondents, aged 18 to 64 years. Structural equation modeling was used to investigate relationships across the model’s constructs. Results In total, 48.70% (n=730) of respondents indicated that they intend to use a COVID-19 tracing app. The most important predictor was the perceived benefits of the app, followed by self-efficacy and perceived barriers. Perceived severity and perceived susceptibility were not related to app uptake intention. Moreover, cues to action (ie, individuals’ exposure to [digital] media content) were positively associated with app use intention. As the respondents’ age increased, their perceived benefits and self-efficacy for app usage decreased. Conclusions Initiatives to stimulate the uptake of contact tracing apps should enhance perceived benefits and self-efficacy. A perceived barrier for some potential users is privacy concerns. Therefore, when developing and launching an app, clarification on how individuals’ privacy will be protected is needed. To sustain perceived benefits in the long run, supplementary options could be integrated to inform and assist users.

The Interpersonal Reactivity Index (IRI; Davis, 1980) is a commonly used self-report instrument designed to assess empathic tendencies. The IRI consists of four separate subscales: Perspective Taking (PT), Fantasy (FS), Empathic Concern (EC), and Personal Distress (PD). The objective of this study was to examine the psychometric properties of a Dutch version of the IRI. The IRI was administered to a Dutch sample of 651 normal functioning adults. The factor structure of the IRI was examined by using confirmatory factor analysis (CFA). The results of the CFA revealed that there is room for improvement and modification of the original theoretical model. The validity of the IRI was tested using internal criteria (i.e., scale intercorrelations) and external criteria (i.e., correlations with subscales of the EQ-i (Bar-On, 1997), the NEO-FFI (Hoekstra, Ormel, & De Fruyt, 1996), Mach-IV (Van Kenhove, Vermeir, & Verniers, 2001), Rosenberg Self-esteem Scale (Rosenberg, 1965), and the WAIS-III (Wechsler, 2000)). Overall, the internal consistency, construct validity, and factor structure of scores from the Dutch version of the IRI suggest that it is a useful instrument to measure people's self-reported empathic tendencies.

To diminish the risk of spreading COVID-19 as society exits the lockdowns, several apps have been developed for contact tracing. These apps register which users have been in proximity of each other. If a user is diagnosed with COVID-19, app users who have been recently in proximity to this person are notified. The effectiveness of these apps highly depends on public support. Therefore, this study investigated the factors that influence app use intention, based on an extended unified theory of acceptance and use of technology model. A survey was administered in Belgium (Flanders) to 1,500 participants aged 18 to 64 years old. Structural equation modeling was used to test the relationships among the model's constructs. Our results indicated that 48.70 percent of the respondents wanted to use the app. The model explained 39 percent of the variance in app use intention. The most important predictor was performance expectancy, followed by facilitating conditions and social influence. Effort expectancy was not related to intention. Moreover, individuals' innovativeness was positively related with app use intention, whereas app-related privacy concerns negatively influenced intention. Based on the results, suggestions are made for policy makers and developers.

Sexting: Adolescents' Perceptions of the Applications Used for, Motives for, and Consequences of Sexting.

Using the actor–partner interdependence model, we explore how various sources of stress and support experienced by fathers and mothers influence their own parenting styles and the parenting styles of the partner. Data from 227 couples were analyzed, with mothers and fathers rating their parenting stress and marital relationship and children rating the parenting styles of both mothers and fathers. Structural equation models revealed actor effects of parenting stress on demanding and responsive parenting styles, as well as partner effects between positive aspects of marital relationship and responsive parenting style. The results further indicate that the strength of these pathways is similar for both mothers and fathers and do not support the hypothesis that the parenting of fathers is more vulnerable than the parenting of mothers.

The family stress model proposes that financial stress experienced by parents is associated with problem behavior in adolescents. The present study applied an actor-partner interdependence approach to the family stress model and focused on low-, middle-, and high-income families to broaden our understanding of the pathways by which the financial stress of mothers and fathers are related to adolescent outcomes. The study uses dyadic data (N = 798 heterosexual couples) from the Relationship between Mothers, Fathers and Children study in which two-parent families with an adolescent between 11 and 17 years of age participated. Path-analytic results indicated that in each of the families the association between parents' financial stress and problem behavior in adolescents is mediated through parents' depressive symptoms, interparental conflict, and positive parenting. Family stress processes also appear to operate in different ways for low-, middle-, and high-income families. In addition to a higher absolute level of financial stress in low-income families, financial stress experienced by mothers and fathers in these families had significant direct and indirect effects on problem behavior in adolescents, while in middle- and high-income families only significant indirect effects were found. The financial stress of a low-income mother also had a more detrimental impact on her level of depressive feelings than it had on mothers in middle-income families. Furthermore, the study revealed gender differences in the pathways of mothers and fathers. Implications for research, clinical practice, and policy are also discussed.
