Two studies are presented to introduce a 10-item short form of the Need for Affect Questionnaire (NAQ-S; cf. Maio & Esses, 2001 ). Study 1 was based on 4 independent samples (German or English language; N (total) = 2,151) and demonstrated the expected factorial structure of the NAQ-S; its measurement invariance with respect to gender, age, and education; and the predicted associations with relevant personality measures. A latent state-trait analysis conducted in Study 2 (N = 140) suggests that most of the reliable variance of the NAQ-S represents stable individual differences.

A growing number of studies have examined the psychological corollaries of using social networking sites (SNSs) such as Facebook, Instagram, or Twitter (often called social media). The interdisciplinary research area and conflicting evidence from primary studies complicate the assessment of current scholarly knowledge in this field of high public attention. We review meta-analytic evidence on three hotly debated topics regarding the effects of SNSs: well-being, academic achievement, and narcissism. Meta-analyses from different laboratories draw a rather equivocal picture. They show small associations in the r = .10 range between the intensity of SNS use and loneliness, self-esteem, life satisfaction, or self-reported depression, and somewhat stronger links to a thin body ideal and higher social capital. There is no indication for potential devastating effects of social media on school achievement; social media use and school grades are unrelated for adolescents. The meta-analyses revealed small to moderate associations between narcissism and SNS use. In sum, meta-analytic evidence is not in support of dramatic claims relating social media use to mischief.

In early adolescence, the time spent using the Internet and video games is higher than in any other present‐day age group. Due to age‐inappropriate web and gaming content, the impact of new media use on teenagers is a matter of public and scientific concern. Based on current theories on inappropriate media use, a study was conducted that comprised 205 adolescents aged 10–14 years (Md = 13). Individuals were identified who showed clinically relevant problem behavior according to the problem scales of the Youth Self Report (YSR). Online gaming, communicational Internet use, and playing first‐person shooters were predictive of externalizing behavior problems (aggression, delinquency). Playing online role‐playing games was predictive of internalizing problem behavior (including withdrawal and anxiety). Parent‐child communication about Internet activities was negatively related to problem behavior.
