MASC 2™

The MASC 2 is a multi-rater assessment with 50-item self-report (MASC 2–SR) and parent (MASC 2–P) rating forms. Both rating forms can be administered using online or paper-and-pencil formats. All formats can be scored online using the MHS Online Assessment Center or locally using Scoring Software.

Reliability

In terms of internal consistency, Cronbach's alpha values for the Total Score and the MASC 2 Scales were strong, with an α of .89 for the Parent Total Score and .92 for the Self-Report Total Score. In terms of test-retest reliability, given an interval of 1-week to 4-weeks between test administrations, excellent test-retest reliability was found, with an r of .93 for the Parent Total Score and .89 for the Self-Report Total Score.

Validity

In order to test the discriminative validity of the MASC 2, data were collected from three samples of children who were previously diagnosed with one of the following Anxiety Disorders: Separation Anxiety Disorder, Generalized Anxiety Disorder, or Social Phobia. Scores from these three groups were compared to scores from the normative sample on the Total Score, as well as on the three Anxiety Scales (i.e., Separation Anxiety/Phobias, GAD Index, Social Anxiety.) These results provide strong evidence for the discriminative validity of the MASC 2. The MASC 2 Total Score can accurately distinguish between clinical and non-clinical groups, and individuals with specific types of anxiety disorders (Separation Anxiety, Generalized Anxiety, and Social Phobia) can be distinguished from each other and from scores obtained by youth from the general population.

The MASC 2 normative samples (Self-Report N = 1,800, Parent N =1,600) are representative of the U.S. and Canadian populations of children and adolescents. Age and gender were balanced across the normative samples, while race/ethnicity, geographic region, and parental education level were statically weighted to match U.S. and Canadian census targets.

A clinical sample of 824 children and youth aged 8 to 19 years diagnosed with GAD, Social Phobia, Separation Anxiety, Panic Disorder, Obsessive Compulsive Disorder, Depression, and ADHD was also collected.
