Primary Outcome Measures:
  • The primary outcome of the study is to determine if CBT is more effective than SMT in reducing distorted beliefs and OCD symptoms in study participants post treatment, as well as six and twelve months post treatment. [ Time Frame: 12 months ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • The secondary outcome of the study is to determine if change in appraisals of intrusive thoughts will mediate symptom change during and after treatment (i.e. follow-up). [ Time Frame: 12 months ] [ Designated as safety issue: No ]

Arms Assigned Interventions
Active Comparator: 1
Cognitive Behavior Therapy (CBT) may include keeping a diary of significant events and associated feelings, thoughts and behaviors; questioning and testing cognitions, assumptions, evaluations and beliefs that might be unhelpful and unrealistic; gradually facing activities which may have been avoided; and trying out new ways of behaving and reacting and using relaxation and distraction techniques.
Behavioral: Cognitive Behavioral Therapy
Participants will be randomly assigned to either immediate treatment or delayed treatment (three month delay). Participants will then be again be randomly assigned to either Cognitive Behavior Therapy (CBT) or Stress Management Therapy (SMT). The delayed participants (wait list control) will be randomly assigned to either of the two active treatment groups in three months time. Both active treatment conditions involve one hours, individual treatment sessions for 12 consecutive weeks by one of the treating psychologists. All participants will also be asked to complete a package of psychometric questionnaires before treatment.
Active Comparator: 2
Stress Management Therapy (SMT) includes relaxation, interaction, biofeedback, exercises, such as muscle stretching exercises, yoga, meditation, time management techniques, and many more.
Behavioral: Stress Management Therapy (SMT)
Participants will be randomly assigned to either immediate treatment or delayed treatment (three month delay). Participants will then be again be randomly assigned to either Cognitive Behavior Therapy (CBT) or Stress Management Therapy (SMT). The delayed participants (wait list control) will be randomly assigned to either of the two active treatment groups in three months time. Both active treatment conditions involve one hours, individual treatment sessions for 12 consecutive weeks by one of the treating psychologists. All participants will also be asked to complete a package of psychometric questionnaires before treatment.

Detailed Description:

Participants will be phone-screened to determine broad suitability and interest in being in the study, as well as availability. Following telephone screening, participants will meet with a clinician who will administer a semi-structured interview to determine diagnostic status followed by a more specific standard semi-structured interview to measure symptom strength in those participants who meet diagnostic criteria of OCD (primary obsessions). Participants will then be invited to join the study. Participants will be randomly assigned to either immediate treatment or delayed treatment (three month delay). Participants will then be again be randomly assigned to either Cognitive Behavior Therapy (CBT) or Stress Management Therapy (SMT). The delayed participants (wait list control) will be randomly assigned to either of the two active treatment groups in three months time. Both active treatment conditions involve one hours, individual treatment sessions for 12 consecutive weeks by one of the treating psychologists. All participants will also be asked to complete a package of psychometric questionnaires before treatment. Participants assigned to the delayed treatment condition will be asked to complete these questionnaires again before proceeding to treatment once they have completed the three month wait. The participants will be re-evaluated at the end of treatment, at six months after treatment, and at one year after treatment, using the same assessment procedure.
