Abstract

Objective

The purpose of this study is to investigate changes in action-proneness (a cognitive and behavioral tendency toward direct action) after a multidisciplinary group intervention, including cognitive behaviour therapy (CBT) and graded exercise therapy (GET).

Methods

Patients with chronic fatigue syndrome (n=62) completed three versions of a Dutch self-report questionnaire evaluating action-proneness retrospectively that is (1) before illness onset, (2) before treatment and (3) after treatment. Significant others (n=62) also gave their opinion about the patients' action-proneness at time points 1 and 2.

Results

Premorbid action-proneness levels considerably dropped after illness onset. After treatment, action-proneness levels significantly increased again, although levels remained below premorbid levels.

Conclusion

High action-proneness retrospectively reported by CFS patients can be adaptively modified by a multidisciplinary group treatment including CBT and GET.

Introduction

Chronic fatigue syndrome (CFS) is a distressing and potentially disabling illness characterized by persistent medically unexplained fatigue, muscular and articular pains, postexertional malaise, and other nonspecific symptoms [1]. A clear cause of the condition is not established, although the pathophysiology of CFS (and the largely overlapping fibromyalgia syndrome) may be based on subtle stress system malfunctions [2].

Many authors believe that since a direct curative treatment for CFS is not available, recovery may be facilitated when patients realistically adapt to their current limitations, at the same time, trying to progressively increase their physical and mental effort tolerance [2]. In a systematic review, both cognitive behavior therapy (CBT) and graded exercise therapy (GET) have been considered evidence-based methods to obtain these goals [3].

In our previous research, we investigated the possible etiopathogenetic role of an “overactive” lifestyle in CFS, which we operationalized as high “action-proneness,” that is, a cognitive and behavioral tendency toward direct action [4]. Maladaptive overactivity patterns may not only precede the illness but may persist after illness onset (e.g., periodic outbursts of activity followed by prolonged periods of rest), constituting an important perpetuating factor [5].

The aim of the present study was to investigate whether, and to which degree, adaptive changes in beliefs, attitudes, and intentions concerning (over)activity occur in CFS patients participating in a multidisciplinary CBT- and GET-based treatment program. The study was part of a larger outcome study, the results of which are reported elsewhere [6].

Participants

Sixty-two consecutively admitted patients (55 female and 7 male, mean age=39.03 years, S.D.=8.61) participated in the study. The majority (87%) had at least higher secondary education, and 80% were married or living together. Only two patients dropped out before the end of the treatment.

Each patient was sent to our CFS Reference Centre at the University Hospitals Leuven by his/her general practitioner. At the end of the multidisciplinary diagnostic screening, a CFS diagnosis was based on the

Results

As shown in Table 1, Table 2, the patients' pretreatment action-proneness levels (M=17.75, S.D.=6.21) were significantly lower than premorbid levels (M=38.27, S.D.=6.65, P<.001). On the other hand, posttreatment action-proneness levels (M=20.23, S.D.=4.65) were significantly higher than pretreatment levels (P=.03) but still significantly lower than premorbid levels (P<.001).

The SOs scored the patients' pretreatment action-proneness also as lower (M=19.95, S.D.=6.97) than the patients' premorbid

Discussion

First, the results of this study are in line with our previous findings that CFS patients describe themselves, before illness onset, as highly “action-prone” [4]. Moreover, as in our former research [5], patients' self-descriptions were paralleled by the opinion of their SOs.

Second, after illness onset, patients' reported action-proneness levels strongly decreased—an expected finding that could be considered a consequence of symptoms and illness-related functional limitations.

Third, when at the

    Citation Excerpt :

    Self-criticism is increasingly conceptualized as a transdiagnostic factor that may play a key role in explaining the high comorbidity between depressive symptoms and FSS [36,37]. Specifically, self-criticism has been shown to be associated with a pattern of over-activity and persistence [38–41], which may lead to a crash of the stress system, typical of both depression [42–45] and functional somatic disorders [38,46–49], because of the ‘wear and tear’ caused by chronic stress and over-activity. In this regard it is also important to consider that self-criticism and both depressive symptoms and FSS share important environmental factors, such as early childhood adversity [50–53] and dysfunctional (e.g., cold and controlling) parenting [54–56].

  • The prevalence and impact of early childhood trauma in Chronic Fatigue Syndrome

    2013, Journal of Psychiatric Research
    Citation Excerpt :

    Early childhood trauma may also have important effects on personality and lifestyle. For instance, we and others have hypothesized that high levels of “action-proneness” and self-critical perfectionism that have been identified in at least a subgroup of CFS patients (Kempke et al., 2011b, in press; Van Houdenhove, Bruyninckx, and Luyten, 2006), may reflect attempts to compensate for feelings of worthlessness and inferiority associated with (emotional) adverse childhood experiences in order to regain a positive sense of self (Kempke et al., 2011a; Van Houdenhove, 1986, 2005; Van Houdenhove and Neerinckx, 1999; Van Houdenhove et al., 2001; Van Houdenhove, Stans, and Verstraeten, 1987). Although this study has a number of strengths, including the diary method approach, several limitations need to be considered.

  • The role of acceptance in chronic fatigue syndrome

    2011, Journal of Psychosomatic Research
    Citation Excerpt :

    Systematic reviews have shown CBT to be effective in improving functioning and reducing fatigue in CFS patients [5]. CBT, along with Graded Exercise Therapy, has also been shown in a non randomised trial to significantly improve “action-proneness” (cognitive and behavioural tendency towards direct action), although not to pre-morbid levels [6]. Research on patients with chronic pain has suggested that attempting to control pain which is uncontrollable (lack of acceptance) is associated with distress and frustration [7,8], reduced physical functioning [9], higher pain identity and more serious perceived consequences [10].
