Patients diagnosed with neurotic and personality disorders were assessed at the 1st, 4th, 8th, and 12th week of treatment using the psychological assessment measures.

A manualized group dynamic psychotherapy conducted at the University Hospital in Kraków, focused on monitoring and enhancing therapeutic alliance and insight development. The intervention targeted patients diagnosed with neurotic and personality disorders. Psychological assessments were conducted at weeks 1, 4, 8, and 12 to track changes in symptoms, resilience, alliance, and insight. The psychotherapy emphasized the interplay between trait-like and state-like components of alliance and insight and their relationship to therapeutic outcomes (symptom reduction and resilience enhancement).

Connor-Davidson Resilience Scale Short Version (CD-RISC-10) is a 10-item scale used to assess resilience, defined as the ability to cope with stress in response to challenging experiences. The full CD-RISC consists of 25 items and has a five-factor structure, both versions displaying sound psychometric properties. Observations made during the development of the original scale indicate that resilience can be modified and improved through appropriate interventions, and greater improvement in resilience scores corresponds to more significant overall treatment outcomes. CD-RISC is one of the most frequently used tools to measure resilience. This study employed the short version, CD-RISC-10, which includes two factors labeled as Endurance and Perseverance. The CD-RISC-10 uses a 5-point Likert scale to assess resilience.

The Symptoms Questionnaire "O" (SQ-O), a validated 187-item self-report tool used to measure the severity of neurotic symptoms across affective, somatic, and behavioral domains. The checklist includes 14 subscales covering different areas of neurotic psychopathology. The SQ-O can be used both diagnostically, to assess the overall severity of symptoms (cut-off scores are sex-adjusted; scores above 165 for men and 200 for women indicate symptoms exceeding the norm), as well as a measure of treatment-related change. This study focused on the overall scale scores measured at specified time points, without analyzing changes in individual subscales. Each item is scored dichotomously (0 = no, 1 = yes).

Psychological Insight Questionnaire (PIQ) is a tool used to assess insight, defined as a series of realizations and discoveries related to personality, relationships, behavioral patterns, and emotions. The questionnaire consists of 23 items rated on a 6-point Likert scale (from 0 - none/not at all to 5 - extreme) to indicate the intensity of each experienced state over the last 7 days. The scale includes two subscales: (1) Avoidance and Maladaptive Patterns Insights and (2) Goals and Adaptive Patterns Insights, both of which demonstrate satisfactory internal consistency (Cronbach's α = 0.93 and 0.85, respectively). Although initially developed to explore the acute and lasting effects of psychedelic use, the content, sound psychometric properties, and simplicity of the PIQ encourage its use in other areas where psychological insight may be critical in predicting psychotherapy outcomes.
