Single Session Narrative Therapy Study

The Patient Health Questionnaire-9 (PHQ-9) is a 9-item validated self-report measure used to screen for depression, diagnose it, monitor its severity, and measure treatment response. The PHQ-9 ranges from 0 to 27 points, with higher scores reflecting more severe symptoms. Scores ≥ 10 indicate moderate depression. This measure was only collected and reported for patient participants.

The Generalized Anxiety Disorder 7-item (GAD-7) is a validated brief self-report tool that measures anxiety symptoms based on the Diagnostic and Statistical Manual of Mental Disorders (DSM) criteria. The total score ranges from 0 to 21, with higher scores indicating greater severity. Scores ≥ 10 indicate moderate anxiety. This measure was only collected and reported for patient participants.

The Remoralization Scale is a validated 12-item self-report measure rated on a 4-point scale ranging from 1 ("Totally disagree") to 4 ("Totally agree") that assesses the level of remoralization. The total score ranges from 12 to 48, with higher scores indicating higher levels of remoralization. This measure was only collected and reported for patient participants.

The Social Connectedness Scale is an 8-item instrument that assesses the degree to which one feels connected to others in their social environment. Items are measured on a 6-point Likert scale ranging from 1 ("Strongly Agree") to 6 ("Strongly Disagree"). Total scores range from 8 to 48 points. Higher total scores indicate a greater sense of social connectedness. This measure was only collected and reported for patient participants.

The State-Trait Assessment of Resilience Scale measures resilience using a state and trait approach, based on the conceptualization of resilience as being influenced by a combination of state and trait factors. This study will only measure the 'Trait' level of resilience, using the trait sub-scale (7-item instrument), which is construed as more distal and enduring. Items are measured on a 4-point Likert scale ranging from 1 ("Disagree") to 4 ("Strongly agree"). Total sum scores are calculated for the sub-scale and range from 7 to 28 points; higher scores reflect greater resilience. This measure was only collected and reported for patient participants.

The Brief Services Evaluation is a 6-item self-report measure assessing patients' perceptions of their skills, ideas, and knowledge related to the primary problem that brought them to counseling. Items are rated on a 6-point Likert scale ranging from 1 ("Strongly disagree") to 6 ("Strongly agree"). Item-level score totals range from 1 to 6. We report item-level changes and significance levels consistent with the Canadian study. The BSE was completed by pilot participants immediately before and one month after their first SSNT session. This measure was only collected and reported for patient participants.

The Acceptability of Intervention Measure is a 4-item measure of perceived intervention acceptability. Items are measured on a 5-point Likert scale 1 ("Completely Disagree") to 5 ("Completely Agree"). Score is a calculated mean that ranges from 1-5. Higher mean scores indicating greater perceived intervention acceptability.

The Intervention Appropriateness Measure is a 4-item measure of perceived intervention appropriateness. Items are measured on a 5-point Likert scale 1 ("Completely Disagree") to 5 ("Completely Agree"). Score is a calculated mean that ranges from 1-5. Higher mean scores indicating greater perceived intervention acceptability.

The Feasibility of Intervention Measure is a 4-item measure of perceived intervention feasibility. Items are measured on a 5-point Likert scale 1 ("Completely Disagree") to 5 ("Completely Agree"). Score is a calculated mean that ranges from 1-5. Higher mean scores indicating greater perceived intervention feasibility.

A 2-item questionnaire evaluating: a) if a patient would like to remain or be taken off the psychotherapy waitlist of [Blinded] clinic (yes or no) b) if the patient selects to remain on the waitlist, what service type they are seeking (Up to 3 single sessions scheduled when needed or 12-16 regularly scheduled sessions). This measure was only collected and reported for patient participants.

The Single Session Impressions and Feedback tool is an 8-item post-session questionnaire which measures patient satisfaction and the degree to which the therapist adhered to key single session narrative therapy principles during the session. Items are measured a 7-point Likert scale from "1" (Strongly Disagree) to "7" (Strongly Agree) with the exception of the final item which is open-entry. Item level scores are reported. Item scores range from 1 to 7. Higher scores indicate greater patient satisfaction and therapist adherence to the intervention. As the SSIFT was designed as a therapist feedback tool, its psychometric properties have not been reported. The measure was only collected and reported for patient participants immediately after their first SSNT encounter.

The Single Session Consultation Feedback Form is a 5-item post-session questionnaire that measures patients' satisfaction with the therapy intervention. Items are measured on a Likert scale from 1 ("Not at all") to 5 ("Very much") with the exception of the final item which is open-entry. A higher score indicates greater satisfaction with the intervention. This measure was only collected and reported for patient participants.
