Registered outcomes10
Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.
| List | Outcome | Time frame | Description |
|---|---|---|---|
| Primary | Auditory Hallucination Rating Scale (AHRS) | Change from Baseline to immediately after treatment and 3 months after treatment | Self-report measure for severity of hallucinations; consists of seven items; Sum can range from 2 to 41; higher values indicate more severe hallucinations |
| Primary | Hallucination Change Scale (HCS) | Change from Baseline to immediately after treatment | Measure for changes in severity of auditory hallucinations; participants rated in percent how much their symptoms had improved (or worsened). The range is thus -100 (symptoms reduced by 100%) to +100 (symptoms worsened by 100%) |
| Secondary | Positive and Negative Syndrome Scale (PANSS) | Change from Baseline to immediately after treatment and 3 months after treatment | Positive Sum Score; conducted by clinical rater; consists of 10 items, range 7-49; higher scores indicate more severe symptoms |
| Secondary | Stroop Task | Change from Baseline to immediately after treatment and 3 months after treatment | Measure of executive functioning, Stroop condition #3 in seconds; higher values indicate longer task duration and worse performance |
| Secondary | Trailmaking Test B | Change from Baseline to immediately after treatment and 3 months after treatment | Measure of visuomotor speed |
| Secondary | Apathy Evaluation Scale | Before, immediately after treatment, and at 3 month follow-up | Total sum of AES score; consists of 18 items; range 18-72, higher values indicate higher degree of apathy |
| Secondary | The Clinical Global Impressions Scale - Severity | Change from Baseline to immediately after treatment and 3 months after treatment | Measure of global functioning; rated by clinician on a 7-point scale, with the severity of illness scale rated from 1 (normal) through to 7 (most severely ill) |
| Secondary | Global Assessment of Functioning - S | Change from Baseline to immediately after treatment and 3 months after treatment | Measure of global functioning - Symptoms, rated by clinician; measures how much a person's symptoms affect their day-to-day life on a scale of 0 to 100, where 0 is severely impacted in daily life by symptoms and 100 is not affected at all |
| Secondary | Dichotic Listening Paradigm | Change from Baseline to immediately after treatment and 3 months after treatment | Measure of executive functioning, forced left condition, percentage reported from left ear |
| Secondary | Dichotic Listening Laterality Index | Change from Baseline to immediately after treatment and 3 months after treatment | Measure of language lateralization, laterality index in non-forced condition, laterality index is computed according to formula: LI=\[(R-L)/(R+L)\]\*100, where "L" and "R" are the number of correct left and right ear responses, respectively. values can range between -100 (only syllables from left ear correctly reported and +100 (only correct syllables from right ear reported) |
