Data for: Personality change goals and plans as predictors of longitudinal trait change in young adults: A replication with an Iranian sample
Design: The study employed a two-phase longitudinal design, with 12 months separating each phase (Phase 1 and Phase 2). Goals and plans were measured at Phase 1, and personality traits were measured at Phase 1 and Phase 2. During each phase, participants were given two months within which to complete the questionnaires. Participants: The sample at Phase 1 comprised 170 students of Yazd University aged 18-28. At Phase 2 (one year later), 160 of the original sample participated, representing an attrition rate of 7%. Of the completers, 61 were male and 99 were female. The average age was 21.12. The 160 completers are used for the basis of the longitudinal analysis presented here. Measures: Trait goals were assessed with the Big Five Trait-Change Goal Inventory (BF-TGI). Plans for change were assessed using the Trait Change Plans Open-Ended Questions, coded for specificity using a 4-point scale (1- no plan, 2- general plan, 3- semi-specific plan, and 4- specific plan). For full descriptions of these measures, see Robinson et al., (2015). Trait levels at T1 and T2 were measured using the 44-item Big Five Inventory (John, Donahue, & Kentle, 1991). All measures were delivered in Farsi using the validated translation arranged for the Robinson et al. (2015, study 2), and were administered online.
