Construction, Validity and Reliability of Academic Self-defeating Behaviour Questionnaire in Adolescents

Conscious and deliberate behaviours that despite of positive consequences finally led to failure are called self-defeating behaviours. The major aim of the current research was “Construction, Reliability and Validity of Academic Self-defeating Behaviour Questionnaire in Adolescents”.

In this descriptive survey study the statistical population included the secondary school students in Tehran in the academic year 2020-2021. The research sample included a total of 1265 person (548 boys and 717 girls) that selected by cluster random sampling methods. To develop the questionnaire, we reviewed previous studies of Academic Self-defeating Behaviour, Cunningham Self-defeating Behavior Questionnaire (54) and investigating components based on theoretical literature.To evaluate the construct validity, data were divided into two groups (633 and 632 people). The first half data were used for exploratory factor analysis and the second half data were used for confirmatory factor analysis.

The results of exploratory factor analysis showed that 35 items have high loading on 3 factors, included "procrastination/self-handicapping, ""inability to goal orientation/performance, " and "inaccurate self-assessment, " which together explained 0/38 of the total variance of questionnaire. After combining the items, confirmatory factor analysis showed that the model has a good fit with the data.Too the internal consistency of the total questionnaire was obtained 0.85.Discussion and

The present questionnaire was developed to investigate academic self-defeating behaviour and our findings revealed that the mentioned questionnaire met desirable validity and reliability, so that it can be used along with other diagnostic tools to assess academic self-defeating behaviour.
