Background/Objective : Based on studies using established psychometric scales, Twenge and coworkers have shown substantial increases in trait anxiety, depressive symptoms and neuroticism in North American population samples since the 1950s. Similar analyses for European samples have not yet been conducted. Our study therefore examined whether similar secular trends exist in German-speaking and British non-clinical samples together with possible connected societal factors. Method : A literature search identified 131 studies ( N = 63,269) using the STAI, BDI or EPI in non-clinical samples between 1964 and 2015. Seven societal factors from national statistics were included. We conducted meta-analyses with displayed means and moderation analyses of publication year for all scales. Results : In contrast to North America results, anxiety, depression and neuroticism showed no increase in the two European populations. Publication year correlated negatively with and moderated trait anxiety (GER) and neuroticism (UK). Most societal factors were highly correlated with year of publication. Trait anxiety and neuroticism were significantly predicted by age at marriage and unemployment rate in German-speaking countries. Conclusion : The difference in secular trends between European and North American samples may indicate society specific developments connected to different societal factors.
