Self-determination Theory (SDT)

Purpose: This study aimed to investigate the critical determinants of perceived well-being in friendship relationships during emerging adulthood. Methodology: A sample of 726 undergraduate students at Ferdowsi University of Mashhad was selected during the Fall semester of 2021-2022 through the convenience sampling method.They completed the Interpersonal Behaviors Questionnaire (IBQ; Rocchi et al., 2017), the Compassionate and Self-image Goals Scale (CSIGS; Crocker & Canevello, 2008), the Basic Need Satisfaction in Relationships Scale (BNS-RS; La Guardia et al., 2000), the Interpersonal Needs Questionnaire (INQ-10; Bryan., 2011), the Friendship Self-Regulation Questionnaire (SRQ-F; Ryan & Connell, 1989), Interpersonal Behaviors Questionnaire-Self (IBQ-self; Rocchi et al., 2017), the State Level Subjective Vitality Scale (SVS-SL; Ryan & Frederick, 1997), the Perceived Relationship Quality Component (PRQC; Fletcher et al., 2000), and the The Basic Empathy Scale (BES; Jolliffe & Farrington, 2006). Data analysis was conducted using Partial Least Squares Structural Equation Modeling. All statistical analyses were conducted using SPSS.25, AMOS.24, and SmartPLS 3.3.3. Findings: The perceived support of basic psychological needs by friends (β=.204), the perceived thwarting of basic psychological needs by friends (β=-.147), the goal in friendship relationships (β=.234), the satisfied basic psychological needs (β=.124), the frustrated psychological needs (β=-.116), and the friendship self-regulation (β= .023) had significant indirect effects on perceived well-being in friendship relationships (p<0.05). Conclusion: The findings demonstrate that self-determination theory provides a coherent framework for explaining perceived well-being in friendships.

This study, drawing on a dual theoretical standpoint constituting ecological systems theory (EST) and self-determination theory (SDT), compared Iranian novice and experienced EFL teachers’ remotivational strategies. The participants, selected based on convenience sampling technique, comprised two equal 32-member groups of novice and experienced EFL teachers teaching different proficiency levels at six language institutes. To gather data, semi-structured interviews were conducted. The results of thematic data analysis indicated that novice and experienced teachers were approximately similar in terms of the emerging theme instances situated within the integrative SDT/EST framework. Nonetheless, novice and experienced teachers were markedly different concerning the number of theme instances for each SDT facet positioned in the EST layers. Moreover, the results of Chi-square test demonstrated significant differences between novice and experienced teachers in terms of the number of themes existing in the SDT/EST frame. The results, enhancing teacher educators’ understanding of the similarities and disparities between novice and experienced teachers’ perceptions of remotivational strategies, can provide teachers and teacher educators with awareness concerning how remotivational strategies are nested across multiple systems while simultaneously being informed by a certain motivation-specific theory.
