Quick Self-Compassion: Italian Validation, Network Analysis, Item Response Theory Analysis, and Correlates of the Self-Compassion Scale Short Form

Objectives: This study aimed to test the factorial structure and gender invariance of the Self-Compassion Scale Short Form (SCS-SF) in the Italian context (Aim 1), underlying relationships among SCS-SF items (Aim 2), questionnaire performance of SCS-SF (Aim 3), and correlations of SCS-SF (and its subscales) with cognitive, affective, and well-being variables (Aim 4). Method: Six questionnaires including the SCS-SF and different correlates were respectively administered to six Italian convenience samples (total n = 2068). We performed confirmatory (ULS estimator) factor analysis (Aim 1), exploratory graph analysis and network analysis (Aim 2), multidimensional item response theory (IRT) analyses (Aim 3), and correlational analyses (Aim 4). We tested Aims 1–3 on the global sample and Aim 4 on the six samples separately. Results: We found a two-factor (hierarchical) solution — which also had strict gender invariance — identifying Compassionate and Uncompassionate Self-Responding (CSR and USR), respectively composed of positive and negative items, while three- and six-factor structures did not hold (Aim 1). The SCS-SF network was structured into the CSR and USR clusters (Aim 2). CSR and — especially — USR had a satisfactory performance in terms of IRT discrimination and information (Aim 3). Correlational analyses supported the convergent and discriminant validity of the scales, showing the cognitive and emotion-regulation strategies associated with self-compassion and confirming that CSR and USR have slightly different correlates (Aim 4). Conclusions: The Italian SCS-SF and its CSR and USR subscales are valid instruments. Future research and interventions can employ CSR and USR to assess different nuances of self-kindness and self-criticism.
