Study Details

Study Description

Brief Summary

Rationale: It is well established that tobacco use has severe health consequences. The prevalence of Tobacco Use Disorder (TUD) is among the highest in populations with Substance Use Disorders (SUD). Despite behavioral and pharmacological treatment options, relapse rates remain high. Therefore, there is a need for additional smoking cessation treatment options that aid long-term abstinence.

A potential interesting intervention is addiction-focused Eye Movement Desensitization and Reprocessing (AF-EMDR) therapy. However, the limited research on AF-EMDR therapy and mixed findings thus far prohibit clinical use. Recently, on the basis of diverse findings thus far, an adjusted AF-EMDR protocol has been developed.

SUMMARY

Rationale: It is well established that tobacco use has severe health consequences. The prevalence of Tobacco Use Disorder (TUD) is among the highest in populations with Substance Use Disorders (SUD). Despite behavioral and pharmacological treatment options, relapse rates remain high. Therefore, there is a need for additional smoking cessation treatment options that aid long-term abstinence.

A potential interesting intervention is addiction-focused Eye Movement Desensitization and Reprocessing (AF-EMDR) therapy. However, the limited research on AF-EMDR therapy and mixed findings thus far prohibit clinical use. Recently, on the basis of diverse findings thus far, an adjusted AF-EMDR protocol has been developed.

Objective: to investigate areas of uncertainty about a possible future definitive RCT using

AF-EMDR as an add-on intervention to a Smoking Cessation Program (SCP), by determining:
  • Feasibility/process outcomes (e.g. recruitment, adherence, treatment fidelity).

  • Preliminary clinical efficacy in order to estimate the effect size for a future power analysis.

Study design: a pilot study with a two-armed randomized controlled design is used in which AF-EMDR + Treatment As Usual (TAU) (Community Reinforcement Approach (CRA) aimed at SUD + a SCP) is contrasted with TAU-only with an intervention phase of three weeks pre- and post intervention assessments and a follow-up after one and three months.

Study population: daily smoking adults, admitted to an inpatient addiction care clinic. A total of 50 eligible participants will be allocated at random to one of two treatment groups.

  • In order to be eligible, patients must meet the following criteria: 1) age ≥ 18 years, 2) good Dutch language proficiency, 3) a DSM-5 diagnosis of Tobacco Use Disorder, 4) smoking, on average, ≥ 10 cigarettes per day pre-admission, 5) A score of at least 5 on a scale from 0 to 10, for motivation and self-efficacy, 6) a planned inpatient stay of ≥ 4 weeks, and 7) written informed consent.

Respondents who demonstrate serious therapy interfering behavior or symptoms that also interfere with TAU will be excluded from participation in this study (e. g. psychiatric or medical crisis that requires immediate intervention).

Intervention: a total of six 45-90 min. sessions of AF-EMDR twice per week added to a SCP embedded in TAU.

Main study parameters/endpoints:
  • Feasibility, design, recruitment and protocol issues.

  • Changes in tobacco craving and smoking behavior.

Arms and Interventions

Arm Intervention/Treatment
Active Comparator: TAU only: Community Reinforcement Approach (CRA) + a regular smoking cessation program

TAU only

Behavioral: TAU only: Community Reinforcement Approach (CRA) + SCP
CRA is a comprehensive cognitive behavioural treatment that focuses on helping people discover and adopt a pleasurable, social and healthy lifestyle that is more rewarding than a lifestyle including substance use. Within CRA a regular smoking cessation program is embedded.
Other Names:
  • CRA (+SCP)
  • Experimental: TAU + Addiction focussed - eye movement desensitization and reprocessing (AF-EMDR) + TAU (CRA)

    TAU + Addiction focussed - eye movement desensitization and reprocessing (AF-EMDR)

    Behavioral: TAU + Addiction focussed - eye movement desensitization and reprocessing (AF-EMDR)
    A total of six 45-90 min. sessions of AF-EMDR therapy with an average frequency of twice per week added to a SCP embedded in CRA. AF-EMD therapy consists of a rationale, installating a treatment goal, desensitasing mental video's, installation of positive cognition, future template and positive ending.

    CRA is a comprehensive cognitive behavioural treatment that focuses on helping people discover and adopt a pleasurable, social and healthy lifestyle that is more rewarding than a lifestyle including substance use. Within CRA a regular smoking cessation program is embedded.

  • Outcome Measures

    Primary Outcome Measures

    1. Retention of participants [1 year]

      The retention of participants from randomization until the last follow-up.

    2. Acceptability in terms of compliance [1 year]

      The acceptability of AF-EMDR to participants in terms of compliance, measured by the total number of sessions attended and the proportion of attended versus non attended (planned) sessions; a higher proportion of attended sessions reflects better compliance.

    3. Acceptability in terms of adherence [1 year]

      The acceptability of AF-EMDR to therapists in terms of adherence to the protocol, measured by the score of an independent rater on an a-priori established adherence rating protocol; a higher score reflects better adherence.

    Secondary Outcome Measures

    1. Proportion of participants [1 year]

      The proportion of patients at the clinic that are potentially eligible and provide informed consent.

    2. The feasibility of the outcome measures [1 year]

      The feasibility of the outcome measures in terms of completion of questionnaires (% per questionnaire and total).

    3. The acceptability of the outcome measures [1 year]

      The acceptability of the outcome measures in terms of Likert-type ratings by participants, therapists and research assistants.

    4. Missing data [1 year]

      Amount of missing data, measured by total number of missing values and the proportion of completed versus missing data.

    Other Outcome Measures

    1. Demographics [1 year]

      Demographics, as inventoried by a structured interview and patient files.

    2. Smoking history [1 year]

      Smoking (cessation history), inventoried by a structured interview and patient files.

    3. DSM-5 [1 year]

      Current DSM-5 diagnoses, inventoried by a structured interview and patient files.

    4. Motivation [1 year]

      Motivation to quit smoking, measured by a Likert-type scale from 0 to 10; a higher score reflects a higher motivation.

    5. Self-efficacy [1 year]

      Smoking cessation self-efficacy, measured by a Likert-type scale from 0 to 10; a higher score reflects a higher self-efficacy.

    6. Nicotine dependence [1 year]

      Severity of nicotine dependence, measured by the Fagerström Test of Nicotine Dependence, providing a score from 0 to 10; a higher score reflects a more severe dependence.

    7. Time to relapse [1 year]

      Time to relapse (from the end of the AF-EMDR intervention, if abstinence is achieved), measured in number of days from the end of the AF-EMDR intervention until first cigarette smoked. The higher the number of days, the longer the time to relapse.

    8. Smoking behavior [1 year]

      Changes from baseline (T0) to T1-T2-T3 in: Smoking behavior, measured by mean number of cigarettes smoked per day over the past 7 days; a higher score means a worse outcome.

    9. Tobacco craving [1 year]

      Changes from baseline (T0) to T1-T2-T3 in: Tobacco craving, as measured by the total score on the Questionnaire of Smoking Urges - Brief version; a higher score means a worse outcome.

    10. Craving related self-control/self-efficacy [1 year]

      Changes from baseline (T0) to T1-T2-T3 in: Craving related self-control/self-efficacy. As measured by a subscale of the Self-control cognitions Questionnaire; a higher score means a worse outcome.

    11. Positive incentive value [1 year]

      Changes from baseline (T0) to T1-T2-T3 in: Positive incentive value. As measured by a subscale of the Self-control cognitions Questionnaire; a higher score means a worse outcome.

    12. Level of Urge [1 year]

      Within AF-EMDR session changes in: Mean Level of Urge, measured by a Likert-type scale from 0 to 10; a higher score means a worse outcome.

    13. Level of Positive Affect [1 year]

      Within AF-EMDR session changes in: Mean Level of Positive Affect, measured by a Likert-type scale from 0 to 10; a higher score means a worse outcome
