This document was not based on experiential expertise alone. It was a rigorous longitudinal research study using validated outcome measures across 298 consumers at 19 PARC services over 12 months. However, the research team notably included consumer researchers (people with lived experience of mental distress) who were integral to recruitment and data collection, enhancing participant comfort and trust while maintaining scientific methodology.

This document was not based on practice wisdom alone. It was a systematic longitudinal research study using standardized outcome measures and statistical analysis. However, the research was informed by practice wisdom - it emerged from calls by practitioners for rigorous evidence to support PARC services, which had been operating based on clinical experience and small localized evaluations with limited scientific validation.

This document was entirely based on research and evaluation insights. It employed a rigorous longitudinal cohort design with validated outcome measures (QPR, K10, WEMWBS, ReQoL, AQoL8D, PNCQ, LCQ) across four time points. The study used mixed-effects linear regression, multiple imputation for missing data, and statistical analysis to evaluate 298 consumers across 19 PARC services, providing systematic evidence of service effectiveness over 12 months.
