Validation of the CYRM/ARM
Various studies have provided information to help confirm the psychometric properties of the CYRM and the ARM. Examples are given below.
| CYRM property | Details |
| Internal consistency/reliability | α=.82 [Jefferies, McGarrigle, & Ungar, 2018] (see the tables below for more) |
| Test-retest reliability | ≥.7 at two-week and three-month intervals [Daigneault et al., 2013] |
| Rasch validation | Good fit to the Rasch model: unidimensional, good fit statistics and internal reliability, and a lack of item bias and problematic local dependency [Jefferies, McGarrigle, & Ungar, 2018] |
| Face validity | For examples see [Daigneault et al., 2013; Ungar et al., 2008] |
| Concurrent validity | e.g., positive correlations with self-esteem (r=.22-.53) [Daigneault et al., 2013], peer support (r=.53) [Kaur, 2018], social skills (r=.62) [Kaur, 2018] |
| Predictive validity | e.g., negative correlations with PTSD (r=-.35) [Zahradnik et al., 2010], positive correlations with acceptance (r=.13-.34) [Daigneault et al., 2013] and academic achievement (r=0.59) [Shakiz & Aftab, 2018] |
| Confirmatory Factor Analysis | e.g., see [van Rensburg et al., 2019] |
| ARM property | Details |
| Internal consistency/reliability | α=.88 [Liebenberg & Moore, 2018] |
| Predictive validity | e.g., BAI (Beck Anxiety Inventory) (r=.27), CES-D (Centre for Epidemiologic Studies Depression Scale) (r=.33), DASS (Depression Anxiety Scale) (r=.26), Rosenberg self-esteeem scale (r=.84) [Antora, 2018] |
