What researchers measure

Primary outcomes

  1. Generalized Anxiety Disorder-7 (Gad-7)

    The Generalized Anxiety Disorder Scale-7 (GAD-7) assesses the severity of anxiety symptoms in adults. The GAD-7 was completed by clients about themselves. Scores range from 0 to 21 with higher scores indicating worse anxiety symptom severity. A score of 8 or greater is generally considered to indicate clinically significant anxiety symptom severity.

    Time frame: Baseline, 3 Months Post Baseline

  2. Patient Health Questionnaire-8 (PHQ-8)

    The Patient Health Questionnaire-8 (PHQ-8) assesses the severity of depression symptoms in adults. The PHQ-8 was completed by clients about themselves. Scores range from 0 to 28 with higher scores indicating worse depression symptom severity. A score of 10 or greater is generally considered to indicate clinically significant depression symptom severity.

    Time frame: Baseline, 3 Months Post Baseline

Secondary outcomes

  1. Health-Related Quality of Life (HRQOL-14) - Healthy Mental Health Days Index

    The Health-Related Quality of Life (HRQOL-14) - Healthy Mental Health Days Index assesses quality of life in terms of the number of days in the past month that clients' feel that their mental health was "not bad." The HRQOL-14 was completed by clients. Respondents report a number from 0 to 30, and the final score indicates better mental health related quality of life.

    Time frame: Baseline, 3 Months Post Baseline

  2. Homework Rating Scale II (HRS II)

    The Homework Rating Scale II (HRS II) assesses levels of homework adherence in cognitive behavior therapy. Total scores range from 0 to 4 with higher scores reflecting better homework adherence. The HRS-II was completed by clients each week and total scores were averaged across weeks between Baseline and 3 Months Post Baseline.

    Time frame: Week 1, Week 2, Week 3, Week 4, Week 5, Week 6, Week 7, Week 8, Week 9, Week 10, Week 11, Week 12, Average across weeks reported.

  3. Assessment of Core CBT Skills (ACCS) - Cognitive Behavioral Therapy Domain

    The Assessment of Core Cognitive Behavioral Therapy (CBT) Skills (ACCS) - Cognitive Behavioral Therapy Domain is an observer rated measure of therapist competence in delivering Cognitive Behavioral Therapy-based interventions. Total scores range from 5 to 20 with higher scores reflecting better competence. The ACCS was used to rate 20% of weekly therapy session audio recordings and total scores were averaged across this 20% of sessions.

    Time frame: Week 1, Week 2, Week 3, Week 4, Week 5, Week 6, Week 7, Week 8, Week 9, Week 10, Week 11, Week 12, Average across weeks reported.

  4. Attitudes Toward Homework Questionnaire (ATHQ) - Positive Homework Effect Scale

    The Attitudes Toward Homework Questionnaire (ATHQ) - Positive Homework Effect Scale assesses therapist perceptions of the positive effects of using homework assignments in psychotherapy. The ATHQ was completed by therapists. Scores range from 1-5 with higher scores indicating therapist perceptions of better positive effects of homework.

    Time frame: Baseline, Post-Trial Therapist Assessment

  5. Working Alliance Inventory - Short Revised (WAI-SR)

    The Working Alliance Inventory - Short Revised (WAI-SR) assesses therapeutic alliance, defined as a collaborative relationship between a therapist and client. The WAI-SR was completed by clients about their perceived therapeutic alliance with their therapist. Scores range from 12-60 with higher scores indicating better therapeutic alliance.

    Time frame: 3 Months Post Baseline

  6. Client Satisfaction Questionnaire - 8 (CSQ-8)

    The Client Satisfaction Questionnaire - 8 (CSQ-8) assesses the level of clients' satisfaction with their outpatient mental health services. The CSQ-8 was completed by clients. Scores range from 8-32 with higher scores indicating higher levels of satisfaction.

    Time frame: 3 Months Post Baseline

  7. Assessment of Core CBT Skills (ACCS) - Homework Domain

    The Assessment of Core Cognitive Behavioral Therapy (CBT) Skills (ACCS) - Homework Domain is an observer rated measure of therapist competence in implementing homework during Cognitive Behavioral Therapy-based interventions. Total scores range from 5 to 20 with higher scores reflecting better competence. The ACCS was used to rate 20% of weekly therapy session audio recordings and total scores were averaged across this 20% of sessions.
