One obstacle here is the lack of a measure to gauge both positive and negative experiences during psychotherapy. We developed and evaluated a new instrument for measuring such experiences. \nMethod: The Positive and Negative Experiences of Psychotherapy questionnaire (PNEP) was developed based on pilot data, a literature review, and two existing scales for measuring primarily adverse experiences during psychotherapy. Mental health care patients (N = 200) anonymously completed and evaluated the PNEP. Subsequently, a sample of professionals (N = 34) who underwent psychotherapy in the context of their training filled in the PNEP twice, with a two-week interval in between. \nResults: The positive and negative experiences subscales of the PNEP were found to possess excellent internal consistencies (αs ≥ .90). The PNEP test-retest reliability was .93 for the positive experiences subscale, and .78 for the negative experiences subscale. For the positive subscale, four factors were extracted: symptom reduction and positive well-being; high quality of therapy and therapeutic relation; personal growth and acceptance, and interpersonal functioning. For the negative subscale, exploratory factor analysis suggested a three-factor solution: escalation of symptoms and emotional distress; low quality of therapy and therapeutic relation; and (self-)stigmatization and dependency. Participants related a median of 13 positive and six negative therapy experiences to their most recent treatment. The most frequently endorsed negative experiences were: having more negative thoughts and memories, feeling emotionally overwhelmed, and an increase in stress due to the therapy. A minority of participants (10.5%) reported no negative treatment experiences. \nConclusions: Ideally, psychological interventions are evaluated for risks and benefits to determine safety and success. The PNEP might be a promising instrument for achieving this goal, although replication and extension of current findings are needed."}}]},{"typeName":"subject","multiple":true,"typeClass":"controlledVocabulary","value":["Social Sciences"]},{"typeName":"keyword","multiple":true,"typeClass":"compound","value":[{"keywordValue":{"typeName":"keywordValue","multiple":false,"typeClass":"primitive","value":"adverse events"}},{"keywordValue":{"typeName":"keywordValue","multiple":false,"typeClass":"primitive","value":"psychotherapy outcome"}},{"keywordValue":{"typeName":"keywordValue","multiple":false,"typeClass":"primitive","value":"positive experiences"}},{"keywordValue":{"typeName":"keywordValue","multiple":false,"typeClass":"primitive","value":"negative experiences"}},{"keywordValue":{"typeName":"keywordValue","multiple":false,"typeClass":"primitive","value":"side effects"}}]},{"typeName":"publication","multiple":true,"typeClass":"compound","value":[{"publicationRelationType":{"typeName":"publicationRelationType","multiple":false,"typeClass":"controlledVocabulary","value":"IsCitedBy"},"publicationCitation":{"typeName":"publicationCitation","multiple":false,"typeClass":"primitive","value":"https://doi.org/10.1002/cpp.3014"},"publicationIDType":{"typeName":"publicationIDType","multiple":false,"typeClass":"controlledVocabulary","value":"doi"},"publicationIDNumber":{"typeName":"publicationIDNumber","multiple":false,"typeClass":"primitive","value":"10.1002/cpp.3014"},"publicationURL":{"typeName":"publicationURL","multiple":false,"typeClass":"primitive","value":"https://doi.org/10.1002/cpp.3014"}}]},{"typeName":"depositor","multiple":false,"typeClass":"primitive","value":"Faculty of Psychology and Neuroscience - Maastricht University"},{"typeName":"dateOfDeposit","multiple":false,"typeClass":"primitive","value":"2023-01-30"},{"typeName":"kindOfData","multiple":true,"typeClass":"primitive","value":["survey data","clinical data","psychological test","textual data"]}]},"dansDataVaultMetadata":{"displayName":"Data Vault Metadata","name":"dansDataVaultMetadata","fields":[{"typeName":"dansDataversePid","multiple":false,"typeClass":"primitive","value":"doi:10.34894/VDK1L5"},{"typeName":"dansDataversePidVersion","multiple":false,"typeClass":"primitive","value":"1.1"},{"typeName":"dansBagId","multiple":false,"typeClass":"primitive","value":"urn:uuid:3783b0d0-4578-4b1b-9870-5c3bc959030d"},{"typeName":"dansNbn","multiple":false,"typeClass":"primitive","value":"urn:nbn:nl:ui:13-c37d2f5e-2c27-4fd4-95bd-173bbf2324c4"}]}},"files":[{"label":"Dataset_Study1_Pilot.sav","restricted":true,"version":1,"datasetVersionId":31799,"dataFile":{"id":354264,"persistentId":"","filename":"Dataset_Study1_Pilot.sav","contentType":"application/x-spss-sav","friendlyType":"SPSS Binary","filesize":99150,"storageIdentifier":"surf://store:1861297d7b7-607eec6fb775","rootDataFileId":-1,"checksum":{"type":"SHA-1","value":"a7548b4902b8ad41a013440418865e91d0d48a24"},"tabularData":false,"creationDate":"2023-02-02","publicationDate":"2024-12-19","lastUpdateTime":"2025-10-14T06:32:36Z","fileAccessRequest":true}},{"label":"PNEP_Data_after_cleaning_Completers_Final_8-12-2020.sav","restricted":true,"version":1,"datasetVersionId":31799,"dataFile":{"id":356685,"persistentId":"","filename":"PNEP_Data_after_cleaning_Completers_Final_8-12-2020.sav","contentType":"application/x-spss-sav","friendlyType":"SPSS Binary","filesize":1018013,"storageIdentifier":"surf://store:1864abb5f40-a7dfafbe6cef","rootDataFileId":-1,"checksum":{"type":"SHA-1","value":"ec1d36bf8995653b7b5f46840cbae10b6ae7d363"},"tabularData":false,"creationDate":"2023-02-13","publicationDate":"2024-12-19","lastUpdateTime":"2025-10-14T06:32:36Z","fileAccessRequest":true}},{"label":"PNEP_Data_after_cleaning_ Noncompleters_Completers.sav","restricted":true,"version":1,"datasetVersionId":31799,"dataFile":{"id":354245,"persistentId":"","filename":"PNEP_Data_after_cleaning_ Noncompleters_Completers.sav","contentType":"application/x-spss-sav","friendlyType":"SPSS Binary","filesize":1274812,"storageIdentifier":"surf://store:1860c6f20fa-b2d30a19f0d6","rootDataFileId":-1,"checksum":{"type":"SHA-1","value":"1a1b21f382b25a3d01952903ef7a4b22dc7e80c6"},"tabularData":false,"creationDate":"2023-02-01","publicationDate":"2024-12-19","lastUpdateTime":"2025-10-14T06:32:36Z","fileAccessRequest":true}},{"label":"PNEP_meting1_meting2_M2_MERGED_COMPLETERS.sav","restricted":true,"version":1,"datasetVersionId":31799,"dataFile":{"id":354246,"persistentId":"","filename":"PNEP_meting1_meting2_M2_MERGED_COMPLETERS.sav","contentType":"application/x-spss-sav","friendlyType":"SPSS Binary","filesize":538938,"storageIdentifier":"surf://store:1860c718dbb-cb5767039441","rootDataFileId":-1,"checksum":{"type":"SHA-1","value":"2f8abbad0ae590c84be372bdf7a9a2213056db70"},"tabularData":false,"creationDate":"2023-02-01","publicationDate":"2024-12-19","lastUpdateTime":"2025-10-14T06:32:36Z","fileAccessRequest":true}}]}}}
