Overview
Brief Summary
The investigators are modifying and testing the preliminary effectiveness and implementation of a Cognitive Behavioral Suicide Prevention for psychosis (CBSPp) intervention. In this phase of the study, CBSPp will be tested in an initial open trial (n = 10) to examine its feasibility and acceptability. Investigators will recruit clients receiving services at a community mental health setting who have a schizophrenia spectrum disorder and recent suicidal thoughts and behaviors to receive the behavioral intervention for 10-weeks. Providers will be recruited and trained to deliver the intervention. Both clients and providers will be assessed at baseline to test our approach to measurement prior to the Aim 2 RCT (registered separately). Clients will be assessed at three additional timepoints (middle of treatment, end of treatment, and 2 months after treatment ends.

Outcomes
Primary Outcomes
Calgary Depression Rating Scale (CDRS)
Time Frame: baseline, mid-treatment (week 5 of treatment), post-treatment (week 10 of treatment), follow-up (2 months after week 10 of treatment)
A scale to measure depression with scores ranging from 0 to 27 and greater scores indicating greater depression. Item 8 of the scale measures suicide thoughts and behaviors.
Positive and Negative Symptom Rating Scale (PANSS)
Time Frame: baseline, mid-treatment (week 5 of treatment), post-treatment (week 10 of treatment), follow-up (2 months after week 10 of treatment)
A scale to measure psychosis with item ratings ranging from 1 to 7. There are 3 sub-scales across 30 questions of the full scale: positive symptom scale (score range 7-49), negative symptom scale (score range 7-49), and general symptom scale (score range 16-112). Scores are summed for each of the 3 sub-scales with higher scores indicating greater presence of symptoms.
Columbia-Suicide Severity Rating Scale (C-SSRS)
Time Frame: baseline, mid-treatment (week 5 of treatment), post-treatment (week 10 of treatment), follow-up (2 months after week 10 of treatment)
A scale to measure suicide thoughts and behavior. The following are C-SSRS items that have binary responses (yes/no): wish to be dead, non-specific active suicidal thoughts, active suicidal ideation with some intent to act and without specific plan, active suicidal ideation with specific plan and intent, preparatory acts or behavior, aborted attempt, interrupted attempt, actual attempt (non-fatal), and suicide death. A numerical suicidal ideation score is assigned for the first 5 binary items ranging from 0 (no ideation) to 5 (active ideation with plan and intent)
Secondary Outcomes
- Beck Hopelessness Scale(baseline, mid-treatment (week 5 of treatment), post-treatment (week 10 of treatment), follow-up (2 months after week 10 of treatment))
- The Entrapment Scale(baseline, mid-treatment (week 5 of treatment), post-treatment (week 10 of treatment), follow-up (2 months after week 10 of treatment))
- The Defeat Scale(baseline, mid-treatment (week 5 of treatment), post-treatment (week 10 of treatment), follow-up (2 months after week 10 of treatment))
