The present study was conducted to investigate the effectiveness of the unified protocol for transdiagnostic treatment. The results obtained provide empirical evidence for the efficacy of an intervention derived from cognitive-behavioral therapies, which can be applied at clinics.
The present findings suggested significant differences between the mean pre-test and the mean post-test in the intervention group. In other words, the unified protocol for transdiagnostic treatment reduced the depression associated with marital problems in the married women. The clinical improvements observed were consistent with studies by de Ornelas Maia et al. (
15), Ito et al. (
17) and Bullis et al. (
16). These findings can be explained by the beneficial effects associated with many advances in the conceptualization and treatment of mood disorders, especially as the recently-proposed cognitive-behavioral theory, on behavioral patterns and maladaptive thinking as important features of emotional disturbances (
24). Cognitive therapy is the standard treatment for depression, as patients with depression often tend to attribute negative events to internal self-conscious sustained and inclusive causes. Having such a documentary style results in reinforcing the notion that negative events are likely to return in the future following different issues, which can cause a lot of frustration (
25). In other words, it is not the situations, events or triggers that directly causes an emotional response; rather, the cognitive assessment of the positions, events or triggers leads to this response. Identifying the thoughts associated with emotions is therefore crucial (
26).
In the fourth module, the protocol is taught to the participants to recognize the role of maladaptive auto-evaluations in creating emotional experiences. The fifth module emphasizes the emotional experience of behavioral components. In this part of the treatment, the therapist helps the authorities identify emotional patterns and emotional-driven behaviors. After the cognitive authority has more to do with the effects of these behaviors on continuing discomfort, measures are taken to change the current patterns of emotional responses (
3). The most recent psychopathological theories emphasize the role of emotions in developing, maintaining and continuing the symptoms of emotional disorders and many other mental disorders (
24). Despite being rooted in cognitive-behavioral conventions, this protocol is unique. This treatment emphasizes the adaptive and functional nature of emotions, and its effectiveness in depressive disorders can be explained by primarily seeking to identify and correct inappropriate attempts, regulate emotional experiences, and therefore facilitate proportional processing and suppress disproportionate emotional responses to internal (visceral) and external symptoms (
27).
The present study found significant differences between the mean pretest and posttest values in the intervention group. In fact, the unified protocol for transdiagnostic treatment reduced mutual avoidance of communication and the demand/withdraw pattern, and increased the mutual constructive communication model in the married women. Confirming these hypotheses is consistent with the findings of Etemadi et al. (
28), who found marital satisfaction to be significantly higher in the intervention compared to the control group. The findings obtained by de Ornelas Maia et al. in 2017 are consistent with the recent hypotheses suggesting that this protocol with an improved emotional management serves as a potential source of improving the quality of life and sexual functioning (
15). As the first explanation, depression appears to be positively correlated with marital conflicts and communication problems in couples (
6,
29), and this relationship appears more significant in women than men (
29,
30). The largest influence on interpersonal performance has been observed in women (
30). Given the negative relationships of marital satisfaction and quality of life with the duration of untreated depression (
31), treating depression in women can predict improvements in marital satisfaction and communication patterns in couples.
According to the present findings, couples who use the mutual constructive model and marital relationships struggle to maintain healthy relationships, avoid abusive behaviors, feel that they understand each other, present themselves well, negotiate to solve communication problems, and are more satisfied with their married life. On the other hand, couples who use demand/withdraw patterns present malicious behaviors, including criticizing, annoying, suggesting another change, not trying to establish and maintain a healthy relationship and avoiding discussing the problem. These couples cannot properly express their feelings, and do not negotiate a solution to their communication problems, which influences their lives and exerts damaging effects on their family (
32). The desirable performance of the family and the mutual constructive communication model predict marital satisfaction (
32,
33).
As a second explanation, emotional regulation is generally considered an important factor for successful interpersonal communication. Recent research suggests significant relationships between marital satisfaction and the interpersonal emotional regulation process. Emotional ordering in women during an unpleasant experience predicts more marital satisfaction in both women and their spouses, which suggests the importance of regulating negative emotions for marital satisfaction in women during conflicts (
34). Given the key role of emotional regulation skills in improving couple’s communication patterns, the unified protocol can be effective in improving the spouse’s communication patterns through improving marital satisfaction. The main hypothesis of this treatment is that people with emotional disorders resort to procedural strategies against maladaptive emotions, and essentially make efforts to avoid or reduce unpleasant emotions.
In line with the present study, Hashemi and Kimiaei found emotion- focused cognitive therapy to reduce the depression caused by marital problems and the patterns of mutual avoidance and demand/withdraw in the intervention group (
35) and Mahlabani Gorgian et al. found emotion-focused couple therapy to be eff ective in treating the depression caused by couples' communication problems (
36).
The present study limitations included selecting the samples from the patients referred to the psychiatric and counseling clinics of Ferdowsi University of Mashhad. The obtained results should therefore be cautiously generalized to other affected individuals. Follow-ups were also not conducted due to time constraints. Given that all the study participants were female, future research is recommended to focus on both genders.
5.1. Conclusions
According to the present findings, the unified protocol for transdiagnostic treatment can be considered a useful short-term cost-effective treatment for improving the symptoms of depression caused by marital problems. Solving interpersonal problems can also help treat depressed patients.
