Key Takeaway
TDG-CBT significantly increases recovery rates and reduces chronic symptom trajectories compared to treatment as usual.

This secondary analysis of a randomized clinical trial evaluated the efficacy of transdiagnostic group cognitive behavioral therapy (TDG-CBT) against treatment as usual (TAU) for patients experiencing persistent physical symptoms in primary care settings.

Over a 12-month follow-up period, participants were categorized into different symptom trajectories based on PHQ-15 scores. The results demonstrated that patients receiving TDG-CBT were significantly more likely to enter a recovery trajectory compared to those receiving standard care. Specifically, the recovery rate was 54.9% in the intervention group versus 28.9% in the TAU group.

Conversely, the prevalence of chronic symptom trajectories was notably lower in the TDG-CBT cohort. Patients receiving treatment as usual showed higher rates of both moderate (49.2%) and severe (21.9%) chronic symptoms compared to those receiving the transdiagnostic intervention.

Clinicians can utilize these findings to improve outcomes for patients with lingering physical complaints. Identifying baseline factors such as clinical severity and socioeconomic vulnerability may further assist in identifying high-risk patients who would benefit most from structured group cognitive behavioral therapy.

Researchers analyzed a clinical trial involving 497 patients who experienced persistent physical symptoms in a primary care setting. The study compared a specific type of group cognitive behavioral therapy, called TDG-CBT, against the usual treatment provided by doctors.

The results showed that patients receiving the specialized group therapy were much more likely to follow a recovery path over 12 months. Specifically, about 54.9% of those in the group therapy saw improvement, compared to only 28.9% of those receiving standard care. In contrast, fewer people in the group therapy program experienced chronic symptoms that remained moderate or severe.

This study is a secondary analysis of an existing trial. While the results are promising for patients with long-term physical issues, it is important to note that more research may be needed to confirm these specific findings. Patients should talk to their healthcare provider to see if this type of group therapy is right for them.

What this means for you:
Group cognitive behavioral therapy showed higher recovery rates for persistent physical symptoms than standard care.

Common questions

What is TDG-CBT and how does it work?

TDG-CBT stands for transdiagnostic group cognitive behavioral therapy. It is a structured group program designed to treat various conditions at once. In this study, it was compared to standard care to see if it helped patients with persistent physical symptoms manage their condition over a 12-month period.

How much better was the group therapy than standard treatment?

The results showed that 54.9% of people in the TDG-CBT group followed a recovery trajectory, while only 28.9% of those receiving standard care did so. Additionally, fewer people in the group therapy program experienced severe or moderate chronic symptoms compared to those receiving standard treatment.

Who is this treatment intended for?

This study focused on patients in primary care settings who were experiencing persistent physical symptoms. The results suggest that this specific type of group therapy may be more effective than usual care for helping these individuals reach a recovery path over the course of one year.

BACKGROUND: The course of persistent physical symptoms (PPS) is heterogeneous, yet little is known about distinct symptom trajectories and their baseline predictors across treatment conditions in primary care. This study aimed to identify PPS trajectories and their associated baseline characteristics in patients receiving treatment as usual (TAU) or transdiagnostic group cognitive behavioral therapy (TDG-CBT). METHODS: Latent Class Growth Analysis (LCGA) was used to identify trajectories of PPS (PHQ-15) over 12 months in 497 participants from the PsicAP randomized clinical trial (TAU: n = 242; TDG-CBT: n = 255). Baseline predictors of trajectory membership were examined using multinomial logistic regression. RESULTS: Three trajectories were identified within each treatment group: recovery, moderate chronic, and severe chronic. Recovery (class 1) was more frequent in TDG-CBT (54.9%) than in TAU (28.9%), whereas moderate chronic (class 2) and severe chronic (class 3) were more common in TAU (class 2 = 49.2%, class 3 = 21.9%) than in TDG-CBT (class 2 = 32.6%, class 3 = 12.6%). In TAU, chronic trajectories were associated with being female, having a partner, and higher baseline depressive symptoms. In TDG-CBT, chronic trajectories were associated with not having a partner, lower income, higher depressive and panic symptoms, and antidepressant use. CONCLUSIONS: TDG-CBT nearly doubles the likelihood of recovery and reduces chronic symptom trajectories compared with TAU. Baseline clinical severity and socioeconomic vulnerability may help identify patients at risk of chronic symptom courses and guide more tailored treatment strategies.
