Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Compliance related to the total number of successful appointments made | From baseline to 6 months (end of therapy) | Compliance will be assessed by calculating the frequency of successful appointments from baseline to 6 months (end of therapy) |
| Number of drop-outs | From baseline to 6 months (end of treatment) | The number of drop-outs will be assessed by calculating the proportion of participants who do not complete the study protocol |
| Acceptability, measured with an ad hoc questionnaire | From baseline to 6 months (end of the treatment) | Acceptability with the intervention will be assessed by an ad hoc questionnaire to measure the dimensions of acceptability: perceived utility, perceived ease of use, barriers, and intention to use |
| Satisfaction with the intervention, measured with the Client Satisfaction Questionnaire (CSQ-8) | From baseline to 6 months (end of the treatment) | Satisfaction with the intervention will be assessed using the CSQ-8. A 4-point Likert scale is used to rate each item (1 = very dissatisfied; 4 = very satisfied), yielding a total score ranging from 8 to 32. A low score (close to 8) indicates low satisfaction with the services received, and a high score (close to 32) indicates high satisfaction with them. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Change in core beliefs, measured with the Brief Core Schema Scales (BSCC) | Changes in baseline scores at 6 months | The change in core beliefs will be assessed using the BCSS. This scale assesses an individual's core beliefs about themselves and others using a 5-point Likert scale (0-4). It comprises 24 items, yielding four scores: negative-self, positive-self, negative-others, and positive-others. Each score is based on six items. No specific cut-off scores have been established for the BCSS, scores are generally interpreted within a range. Higher scores generally indicate a greater endorsement of the beliefs represented by that subscale. |
| Change in safety behaviour severity, measured with the Safety Behaviour Questionnaire (SBQ) | Changes in baseline score at 6 months | The safety behaviour severity will be assessed using the SBQ. This scale consists of 56 items rated on a 4-point Likert scale, where 0 = never and 3 = always. Specific cut-off scores haven't been established for the SBQ. Higher scores indicate greater frequency of use of safety behaviours. |
| Change in paranoid ideation, measured with the Spanish Green Paranoid Thought Scale (S-GPTS) | Changes in baseline scores at 6 months | The change in paranoid ideation will be assessed using the S-GPTS. This scale consists of a total of 32 items rated on a 5-point Likert scale from 1 (Not at all) to 5 (Completely). The items are grouped into two scales of 16 items. Scale A assesses social reference ideas relevant to paranoia, while Scale B assesses persecutory thoughts. Scores on each scale range from 16 to 80 points, with higher scores reflecting a greater level of paranoid thinking. No cut-off points have been established. |
| Change in functioning severity, measured with the Personal and Social Performance scale (PSP) | Changes in baseline scores at 6 months | The change in functioning severity will be assessed using the PSP scale. The PSP scale evaluates four domains: Socially Useful Activities, Personal and Social Relationships, Self-Care, and Disturbing and Aggressive Behaviours. Each domain is rated on a 6-point severity scale, which is then converted into a 10-point band score for that domain. A total score is derived from the four domain scores, resulting in a single score between 1 and 100. No cut-off score is available. Higher scores indicate better functioning across all domains, with more severe functional difficulties reflected in lower scores. |
| Change in self-perceived functionality severity, measured with the Self-perceived Functionality in people with Psychotic disorders (FAP-10) | Changes in baseline scores at 6 months | The change in self-functionality will be assessed using the FAP-10. This questionnaire includes 10 items that are scored on a Likert scale ranging from 4 (Always) to 0 (Never). The total score is the sum of the scores for each item. The total score ranges from 0 (poor functionality) to 40 (excellent functionality). |
| Change in the severity of psychotic symptoms, measured with the Positive and Negative Syndrome Scale (PANSS) | Changes in baseline scores at 6 months | The severity of psychotic symptoms will be assessed using the PANSS. This scale includes 30 items (7 for positive symptoms, 7 for negative symptoms, and 16 for general psychopathology). A 7-point Likert scale is used to rate each item (1 = not present; 7= most severe). The total score is the sum of all items. No specific cut-off scores have been established for the PANSS. The higher the score, the greater the clinical severity. |
| Change in recovery, measured with the Questionnaire about the Process of Recovery (QPR) | Change in baseline scores at 6 months | The change in recovery will be assessed using the QPR. It is a 15-item scale. Each item is rated on a 5-point Likert scale, from 0 (strongly disagree) to 4 (strongly agree), and the items are added together to obtain a total recovery score. Higher scores indicate greater recovery. No cut-off scores are available. |
| Change in clinic insight, measured with the Scale Unawareness of Mental Disorders (SUMD) | Changes in baseline scores at 6 months | The change in clinic insight will be assessed using the SUMD. It consists of three items that explore the degree of insight a person has into their mental disorder, the effects of medication, and the social consequences. Each item is scored from 0 to 5, where 0 indicates that the item is not relevant or cannot be assessed, and 5 indicates a lack of awareness. No cut-off points are available. |
| Change in cognitive insight, measured with the Beck Cognitive Insight Scale (BCIS) | Changes in baseline scores at 6 months | The change in cognitive insight will be assessed using the BCIS. The BCIS assesses cognitive insight, specifically self-reflectiveness and self-certainty, in individuals with psychosis. It's a 15-item self-report measure where participants rate their agreement with statements on a scale of 0 to 3. The BCIS yields two subscale scores (self-reflectiveness and self-certainty) and a composite Reflectiveness-Certainty (R-C) index score. The R-C index is calculated by subtracting the self-certainty score from the self-reflectiveness score. Higher R-C index scores indicate greater cognitive insight. Cut-off scores: low cognitive insight, scores of 3 and below; moderate cognitive insight, scores of 4 to 9; and high cognitive insight, scores of 10 and above. |
| Presence of adverse events, measured with an ad hoc clinical interview | From baseline to 6 months (end of the intervention) | Safety during the intervention will be assessed by collecting the presence of adverse events using an ad hoc clinical interview |
| Change in quality of life, measured with the Quality of Life Index (QLI-sp) | Changes in baseline scores at 6 months | The change in quality of life will be assessed using the QLI-sp. It is a 10-item questionnaire that assesses various aspects of health-related quality of life. It is scored on a scale of 1 to 10 points, with a higher score corresponding to a better quality of life. No cut-off scores are available. |
| Change in severity of hallucinations and delusions, measured with the Psychotic Symptom Rating Scales (PSYRATS) | Changes in baseline scores at 6 months | The severity of hallucinations and delusions will be assessed using the PSYRATS. It consists of two subscales, one for hallucinations and one for delusions, each with 17 items, with Likert-type responses ranging from 0 to 5. The final score is obtained by adding the scores for each item. It can range from 0 to 44. No specific cut-off scores have been established for the PSYRATS. The higher the score, the more severe the hallucinations/delusions. |
| Change in depression severity, measured with the Calgary Depresión Scale for Schizophrenia (CDSS) | Changes in baseline scores at 6 months | The depression severity is assessed using the CDSS. This scale includes 9 items that are scored with a Likert scale that ranges from 0 (absent) to 3 (severe). The total score is the sum of all items. The higher the score, the greater the clinical severity. To identify the absence/presence of depression, a score ≥ 5 is the cut-off point. |
| Change in the delusional conviction severity measured with the delusional conviction-analogue visual scale (DC-VAS) | Changes in baseline scores at 6 months | Change in the delusional conviction severity will be assessed using the DC-VAS. This scale rates the degree of conviction of the delusional idea from 0 to 10. |
