This study aimed to examine differences in gender, age, and psychopathology, according to the perfectionism level, and to analyze how perfectionism dimensions contribute to the development of psychological strengths and difficulties in children. Participants were 319 Spanish students (52.4% girls) between 7 and 11 years old (M = 9.38, SD = 1.15). Children completed self-reported measures of perfectionism and psychological strengths and difficulties. The sample was divided into groups based on the perfectionism level (high, medium, and low). A one-way ANOVA (Analysis of variance), t-test, Pearson correlations, and 3-step hierarchical regression analyses were run. Results showed that 27.6% of the children belonged to the high perfectionism group, characterized by an elevated Socially Prescribed Perfectionism (SPP). Compared to girls, boys presented higher scores in all perfectionism measures. The younger children presented higher SPP and lower Self-oriented Perfectionism-Critical (SOP-Critical) than the older group. High perfectionism was related to psychological problems. The SOP-Critical increased the likelihood of developing emotional symptoms and total difficulties, and SPP was associated with behavioral and peer problems. In contrast, Self-oriented Perfectionism-Striving (SOP-Striving) was related to greater prosocial behavior. This research has important implications for the design of transdiagnostic strategies targeting the prevention and intervention of psychological difficulties in schoolchildren.

Effectiveness of video-feedback with cognitive preparation to treat anxiety problems (especially social anxiety) has been scarcely explored on children. Super Skills for Life (SSL) is a CBT-based intervention to reduce anxiety and comorbid problems that, apart from social skills training and behavioural activation, integrates video-feedback with cognitive preparation. This study aimed to evaluate SSL effects, implemented in a school setting, on social performance and to test self-concept and social skills as potential mediators of pre- and post-test changes in social anxiety and generalized anxiety. Sample comprised 57 children aged 8–11 years with emotional symptoms. Children were video recorded in the first and last session to assess social performance. Anxiety and self-concept measures were completed by children pre-test and post-test. Participants reduced anxiety behaviours and improved social and communication skills after treatment. In general, girls showed better social performance than boys, but SSL impact was greater in males. Social self-concept was the only mediator of change in pre- to post-treatment social anxiety. This study provides evidence of SSL to improve children’s social performance and reduce anxiety through video-feedback with cognitive preparation. Improving social concept seems essential to reduce social anxiety. An SSL programme is an ideal prevention protocol for anxious children.

Anxious children report a more negative perception of their social performance and increased nervous behaviors. The video-feedback with cognitive preparation allows children to contrast and modify their negative social self-image, increasing their self-confidence and decreasing anxiety behaviors. This study aimed to examine the effectiveness of the Super Skills for Life (SSL) program in improving social performance in a sample of children with emotional symptoms. Results indicated that both objective and subjective evaluation showed positive effects of the SSL program on the children’s social performance, enhancing their social skills and reducing anxiety behaviors in social situations, both during the program and in the last session. Girls felt more comfortable and showed better speech and social performance than boys. Our findings increase the evidence about the short-term effects of the video-feedback with cognitive preparation of the SSL program and provide a useful transdiagnostic protocol for application in the clinical setting.
