Objective: To evaluate the effectiveness of a web-based protocol, ModerateDrinking.com (MD; "www.moderatedrinking.com") combined with use of the online resources of Moderation Management (MM; "www.moderation.org") as opposed to the use of the online resources of MM alone. Method: We randomly assigned 80 problem drinkers to…

Examined factors associated with research attrition in a long-term follow-up study (48 months). Researchers attempted to contact all randomized participants, not just those who completed treatment. The analyses deal primarily with refusal, the main reason for attrition. Short-term outcome did not predict refusal. The findings, if generalizable,…

Analyzes the attrition dilemma and reviews the methods used to compensate for data loss. Argues that attrition is not utlimately a problem of bias but a problem of lack of information. Offers a reformulation that integrates single-case studies with traditional group comparison methodology in an attempt to find optimal causal relations of…

In seven articles methods of enhancing clinical practice through empirical approaches and realistic approaches and realistic research are discussed including: (1) Cronbach's method of intensive observation; (2) intensive monitoring of treatment strength, integrity, and effectiveness; (3) the use of dependent measures; (4) drawing valid conclusions…

Research should be supplemented with measures that do not require respondent cooperation. Unobtrusive'' measures were developed in this study to describe each ward in a state hospital, including such items as use of window curtains and style of staff dress. This ward profile'' correlated with such criteria as readmission rate, length of stay,…

Delineates and explains essential characteristics of single-case research methodology applied within domain of psychotherapy research. Presents single-case research as subclass of intrasubject research in which aggregation across subjects is avoided and generality of one's findings is addressed through replication on case-by-case basis.…

Presents case study research strategy that can be used to develop new psychotherapeutic treatments, test theorized mechanisms of action, and obtain initial outcome data of type needed to support treatment outcome grant applications. Illustrates strategy by two case studies of new psychotherapeutic intervention for patients with coexisting…

To determine the extent to which published randomized controlled trials (RCTs) of psychotherapy can be generalized to a sample of outpatients, the authors matched information obtained from charts of patients who had been screened out of RCTs to inclusion and exclusion criteria from published RCT studies. Most of the patients in the sample who had…

Describes common methodological inadequacies in research on treatment of obesity and suggests alternatives. Importance of multiple measurement of outcome is emphasized. Merits of alternative single-subject and between-groups experimental designs are discussed. Reasons for conspicuous lack of long-term follow-ups are analyzed. Recommendations for…

Kent criticizes Patterson's study on treating the behavior problems of boys, on several methodological bases concluding that more rigorous research is required in this field. Patterson answers Kent's criticisms arguing that they are not based on sound grounds. Patterson offers further evidence to support the efficacy of his treatment procedures.…

This study examines the modification of smoking behavior resulting from smoking on command of a tape-recorded message. Neither paced groups nor the self-paced control group significantly differed in reductions in smoking at six-month follow-up. Cognitive dissonance is suggested in explanation of initial smoking reductions for self-paced subjects.…

Single-case designs make available areas not easily studied in group research and make demands on an investigator that are not easily met in clinical situations. Single-case designs appear relatively straightforward, which may foster problems. Best guide for interpretation is recognition of logic of designs and common methodological problems.…

The major youth psychotherapy meta-analyses have relied on published studies, which may have led to biased effect size estimates. To examine this possibility, the authors compared 121 dissertations with 134 published studies and found the following: (a) few differences on individual methodological variables, but, overall, stronger methodology in…

The authors used cross-cultural methodology to examine the demand-withdraw pattern of marital communication. In Western countries, women usually make more demands, whereas men are more likely to withdraw. But the recently advanced marital structure hypothesis suggests that this pattern can be altered by gender roles and beliefs, particularly in…
