Esaminare gli effetti di un focus terapeutico sui ricordi positivi sulla salute post-trauma
Esame e perfezionamento di un nuovo trattamento per il disturbo da stress post-traumatico: tecnica di elaborazione dei ricordi positivi (PPMT)
Il disturbo da stress post-traumatico (PTSD) ha conseguenze devastanti per la salute. Gli interventi sul disturbo da stress post-traumatico basati sull'evidenza affrontano l'onere sostanziale del disturbo da stress post-traumatico sulla salute degli individui e delle società; tuttavia, diverse persone che ricevono questi interventi abbandonano e non tutte le persone sperimentano un miglioramento dei sintomi di PTSD. Inoltre, questi attuali interventi sul disturbo da stress post-traumatico prendono di mira principalmente i ricordi del trauma. In particolare, prove crescenti suggeriscono che i sintomi di PTSD sono correlati anche a difficoltà nella codifica e nel recupero di ricordi positivi.
Pertanto, lo studio proposto esaminerà gli effetti e gli obiettivi alla base di una nuova tecnica PTSD incentrata sulla narrazione e sui dettagli dei ricordi positivi: la tecnica dell'elaborazione delle memorie positive (PPMT). Metodologicamente, 70 individui saranno assegnati in modo casuale a PPMT vs. Consulenza di supporto (SC) per questo studio.
Gli obiettivi dello studio proposto includono (1) l'esame degli effetti del PPMT sulla gravità dei sintomi del disturbo da stress post-traumatico da stress e sulla disregolazione dei sistemi di stress (ovvero, il risveglio dell'alfa amilasi salivare [sAA] e il cortisolo); (2) esaminare i meccanismi alla base degli effetti del PPMT; e (3) raffinazione del PPMT. Si ipotizza che il braccio PPMT riporterà maggiori riduzioni della gravità del disturbo da stress post-traumatico e dei rapporti sAA/cortisolo. Inoltre, si ipotizza che il miglioramento dell'affetto correlato alla PPMT media l'associazione tra il braccio dello studio (PPMT vs. SC) e i cambiamenti nella gravità del disturbo da stress post-traumatico. Infine, i partecipanti allo studio riceveranno un feedback sulla fattibilità, il formato e il contenuto del PPMT per perfezionare il PPMT.
Lo studio proposto può fornire prove preliminari sul potenziale significato di prendere di mira i ricordi positivi negli interventi PTSD.

Comparatore attivo: Elaborazione della tecnica dei ricordi positivi (PPMT)
I partecipanti ricevono 5 sessioni di Processing of Positive Memories Technique (PPMT) di 60 minuti per PTSD seguendo le procedure di trattamento come delineato nel manuale di terapia PPMT.
|
PPMT comprende 5 sessioni incentrate sull'identificazione e l'elaborazione di ricordi positivi.
Nella Sessione 1-5, i partecipanti raccontano i dettagli di un ricordo positivo ed elaborano il ricordo positivo per suscitare valori, affetti, punti di forza e pensieri positivi.
|
|
Comparatore attivo: Consulenza di supporto (SC)
I partecipanti ricevono 5 sessioni di consulenza di supporto (SC) di 60 minuti.
SC include una discussione sul diario di monitoraggio quotidiano e l'esplorazione di problemi e preoccupazioni attuali.
|
SC è un trattamento di 5 sessioni, attivo e non specifico somministrato settimanalmente, che include una discussione del diario di monitoraggio quotidiano e l'esplorazione di problemi e preoccupazioni attuali.

Awakening Salivary Alpha Amylase to Cortisol Ratio
Lasso di tempo: 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.

Positive and Negative Affect Schedule
Lasso di tempo: 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. |
