Cognitive therapy and exposure in vivo in the treatment of obsessive compulsive disorder.

The present study is the first controlled study that evaluates the effects of cognitive therapy along the lines of Beck (1976) [Cognitive therapy and the emotional disorder. New York: International University Press] and Salkovskis (1985) [Behaviour Research and Therapy, 23, 571-583] in obsessive compulsive disorder (OCD) and compares these effects with those of self-controlled exposure in vivo with response prevention. Seventy-one patients were randomly assigned to either cognitive therapy or exposure in vivo. In each treatment condition seven patients dropped out. Both treatments consisted of 16 sessions. Cognitive therapy as well as exposure in vivo led to statistically significant improvement. Multivariate significant differences suggesting a superior efficacy of cognitive therapy in comparison to exposure in vivo on the obsessive compulsive measures and on the measures for associated psychopathology. However, no univariate differences were found. Further, in both treatment conditions a considerable percentage of the patients was rated as "recovered". Significantly more patients were rated as "recovered" in the cognitive therapy. The results show that this form of cognitive therapy is an effective treatment for OCD and suggest that cognitive therapy may be even more effective than exposure in vivo.

Do patients suffering from obsessions alone differ from other obsessive-compulsives?

The aim of this study was to determine whether a group of 48 patients with obsessions and compulsions differed from a group of 26 patients with obsessions alone, on the basis of demographic variables, variables relating to obsessive-compulsive neurosis, psychological variables and treatment outcome. It was found that they differed significantly in the following areas: marital status, level of education, age at onset of complaints, psychoactive medication taken when admitted for treatment, severity of obsessive-compulsive complaints, depression and intelligence. No difference was found as far as treatment outcome was concerned. Patients suffering from obsessions alone, would appear to form a distinct sub-group within the group of obsessive-compulsive patients as a whole.

Hypnotherapy and contractures of the hand.

Contractures of the hand are rather uncommon conversion phenomena. As yet, very little is known about treatment. After a brief overview of the literature on the various treatment strategies, we describe the treatment of four patients. There are indications that a complaint-centered approach, which attempts to influence the symptom directly, produces positive results. Hypnotherapeutic techniques were used in the four patients described here. Treatment resulted in improvement in three of the four.

Hypnosis: placebo or nonplacebo?

According to Grünbaum's definition of placebo, a therapeutic procedure can be considered a nonplacebo if it can be demonstrated that its effects are produced according to the theory upon which the therapy is based. If the theory is adopted that hypnotic effects depend upon mobilization of the patient's hypnotizability, which is a measurable characteristic, a testable theory is provided. Experimental literature is reviewed that shows that placebo effects are not related to hypnotizability. Clinical outcome studies make it clear that results of hypnotherapy are related to hypnotizability in some disorders such as pain and anxiety, but not in the treatment of addiction or habit disorders. An example of a procedure is given in which hypnosis is nonetheless usefully applied for its placebo value as a method to generate positive expectancies.

Hypnosis and conversion disorders.

A review of the literature shows that presently held views on the relation between hypnosis and conversion disorders had their origin in the previous century. This also holds for therapeutic techniques as they are still applied today. A case report illustrates that successful symptom removal may be independent of the patient's hypnotizability and of the techniques used.

Exposure and response prevention in patients with obsessions.

The outpatient treatment of patients with obsessions alone is often said to be less successful compared to the outpatient treatment of patients with both obsessions and compulsive symptoms. This article presents the outcome of the treatment of 26 obsessive patients. The success rate, measured after 10 treatment sessions, was 73%. At follow-up after 12-36 months, improvement appeared to have been maintained or to have increased in 61.5% of the patients, figures comparable to the outcome of patients with both obsessions and compulsions.
