Positive communication will be measured using the Communication Skills Test (CST), a 10-item assessment of self-reported use of adaptive communication skills (e.g., paraphrasing, time-out). Responses use a 7-point Likert-type scale and are averaged to range from 0 to 7, with higher scores representing better communication skills.

The Brunnsviken Brief Quality of life scale (BBQ) measures subjective quality of life validated for use with both clinical and non-clinical samples, forming an overall life satisfaction score comprised of six life domains (Leisure time, View on life, Creativity, Learning, Friends and Friendship, and View of self) assessed with two items each (importance and satisfaction). Scores are calculated by summing the products of the satisfaction and importance scores for each domain. Sum scores can range from 0 to 96, with higher scores indicating better quality of life.

Psychological distress will be measured with the Depression, Anxiety, and Stress Scale (DASS-21), a 21-item self-report questionnaire measuring three dimensions of negative emotional states. Each of the three dimensions is measured with 7 items on a 0 to 3 point scale, and total scores are calculated by summing the items and then doubling the sum score for equivalence to the longer DASS-42. Total scores for the three dimensions range from 0 to 42.
