Undersøker effekten av et terapeutisk fokus på positive minner på posttraumehelse

6. august 2026 oppdatert av: Ateka Contractor, University of North Texas, Denton, TX

Undersøkelse og forfining av en ny behandling for posttraumatisk stresslidelse: Behandling av positive minner teknikk (PPMT)

Posttraumatisk stresslidelse (PTSD) har ødeleggende helsekonsekvenser. Evidensbaserte PTSD-intervensjoner adresserer den betydelige belastningen av PTSD på helsen til individer og samfunn; Imidlertid faller flere individer som mottar disse intervensjonene ut, og ikke alle individer opplever bedring i PTSD-symptomer. Dessuten er disse nåværende PTSD-intervensjonene primært rettet mot traumeminner. Spesielt tyder økende bevis på at PTSD-symptomer er relatert til vanskeligheter med å kode og hente positive minner også.

Derfor vil den foreslåtte studien undersøke effekter av og mål som ligger til grunn for en ny PTSD-teknikk fokusert på å fortelle og detaljere positive minner - Processing of Positive Memories Technique (PPMT). Metodisk vil 70 individer bli tilfeldig tildelt PPMT vs. Supportive Counseling (SC) for denne studien.

Målet med den foreslåtte studien inkluderer (1) å undersøke PPMTs effekter på alvorlighetsgraden av PTSD-symptomer og stresssystemers dysregulering (dvs. vekke spytt alfa amylase [sAA] og kortisol); (2) undersøke mekanismer som ligger til grunn for PPMTs effekter; og (3) raffinering av PPMT. Det antas at PPMT-armen vil rapportere større reduksjoner i PTSD-alvorlighet og sAA/kortisol-forhold. Videre er det antatt at PPMT-relatert forbedret affekt vil formidle assosiasjonen mellom studiearm (PPMT vs. SC) og endringer i PTSD-alvorlighet. Til slutt vil det bli innhentet tilbakemeldinger fra studiedeltakerne om PPMTs gjennomførbarhet, format og innhold for å avgrense PPMT.

Den foreslåtte studien kan bidra med foreløpige bevis på den potensielle betydningen av å målrette positive minner i PTSD-intervensjoner.

Deltakergruppe / Arm
Intervensjon / Behandling
Aktiv komparator: Processing of Positive Memories Technique (PPMT)
Deltakerne får 5 60-minutters behandlinger av positive minner Technique (PPMT) økter for PTSD etter behandlingsprosedyrene som er skissert i PPMT terapihåndbok.
Atferdsmessig: Processing of Positive Memories Technique (PPMT)
PPMT består av 5 økter med fokus på å identifisere og behandle positive minner. I økt 1-5 forteller deltakerne detaljer om ett positivt minne, og behandler det positive minnet for å fremkalle positive verdier, affekt, styrker og tanker.
Aktiv komparator: Støttende rådgivning (SC)
Deltakerne får 5 60-minutters støttende rådgiving (SC) økter. SC inkluderer en diskusjon av den daglige overvåkingsdagboken og utforskning av aktuelle spørsmål og bekymringer.
Atferdsmessig: Støttende rådgivning (SC)
SC er en 5-sesjons, aktiv og uspesifikk behandling administrert ukentlig, som inkluderer en diskusjon av den daglige overvåkingsdagboken og utforskning av aktuelle problemer og bekymringer.

Tidsramme
Awakening Salivary Alpha Amylase to Cortisol Ratio
Tidsramme: 3 times each day for 2 consecutive days prior to first therapy session
Via a passive drool procedure, participants provided 3 whole saliva samples each day for 2 consecutive days both prior to PPMT/SC: (1) immediately upon awakening, (2) 30 minutes post-awakening, and (3) 60 minutes post-awakening. For each marker, for each day, area under the curve with respect to ground (AUCg) was calculated. The two-day average AUCg of sAA was then divided by the two-day average AUCg of cortisol to create the ratio variable. Higher sAA/cortisol ratio indicates greater stress system dysregulation and sympathetic nervous system dominance.

Via a passive drool procedure, participants provided 3 whole saliva samples each day for 2 consecutive days one week following PPMT/SC: (1) immediately upon awakening, (2) 30 minutes post-awakening, and (3) 60 minutes post-awakening. For each marker, for each day, area under the curve with respect to ground (AUCg) was calculated.

Positive and Negative Affect Schedule
Tidsramme: Baseline

The 20-item Positive and Negative Affect Schedule (PANAS) examined past-week positive and negative affect levels. There were 10 items for each of the PANAS-Positive and PANAS-Negative subscales, which measure past-week positive and negative affect respectively.

Response options ranged from 1 (not at all/very slightly) to 5 (extremely), with the possible range being from 10 to 50 for each subscale. Higher scores mean more self-reported positive affect and negative affect for the PANAS-Positive and PANAS-Negative subscales respectively.
