believe that most psychotherapy researchers, including readers of this In Review, have had the following experience. A friend or relative, whom you have not seen for a while, inquires about the status of your research. With minimal hesitation, you offer something in layman's terms such as: I am trying to find out how effective different forms of psychotherapy [efficacy study] or I am trying to find out which psychotherapy works best with which type of patient [matching study] or I am trying to find out which type of patients work well together in a psychotherapy group [composition study]. Although rather straight-forward and seemingly clear, these examples are often met with a puzzled look that conveys the message Are you still doing that? or Have you found anything new yet? Just as there seems to be a wish among the general public to hear about new discoveries, there is a wish among psychotherapy researchers to be able to report new discoveries, not to mention breakthroughs. Unfortunately, in psychotherapy research, breakthroughs are few and far between, if they occur at all. For this reason, it was with definite interest and excitement on my part in anticipating the findings of the 2 papers in this In Review.1'2 They are devoted to New Psychotherapies for Mood and Anxiety Disorders1 and to Promising Psychotherapies for Personality Disorders (PDs). These disorders are very prevalent. Discoveries of effective new therapies for these disorders could be a considerable contribution to the field, particularly if they are shown to be more effective or less costly than previous therapies. In the first review article, Dr Shannon Wiltsey Stirman, Ms Katherine Toder, and Dr Paul Crits-Christoph1 identify so-called new therapies: 5 for mood disorders, 3 for posttraumatic stress disorder, and 2 for other anxiety disorders. These therapies were first introduced, or findings associated with them first reported, in the literature in the past 5 years (2004-2009). The therapies carry such names as acceptance and commitment therapy, behavioural activation therapy, and positive psychotherapy. Evidence of efficacy, effectiveness, and specificity vary considerably among the therapies. While the authors attempt to maintain a sense of optimism about the benefits of future research with new therapies, a sense of disappointment permeates their conclusions. This is due largely to their conclusion that although substantial benefit is associated with the new therapies, none has been found to surpass the benefits of previous therapies. The authors present an engaging discussion that provides context for considering these new developments for the treatment of mood and anxiety disorders. The second review article2 had similar objectives, although with a markedly different sample of patients, those with PDs. In addition, the period of investigation was briefer (the past 3 years) and only randomized controlled trial (RCT) studies were included. Interestingly, the authors avoided calling treatments new, instead electing to call them promising. Perhaps they sensed how difficult it really is to clearly define new. Dr George Hadjipavlou and Dr John S Ogrodniczuk2 reflect an increasingly positive pattern of response to treatment and prognosis. They identify numerous so-called psychotherapy packages that are backed up by evidence from the RCTs. Examples are mentalization-based therapy, transference-focused psychotherapy, and dialectical behavioural therapy. The authors provide an excellent discussion of the current state of psychotherapeutic treatment for PDs. They also correctly identified several limitations associated with studies in this area. Among these is the nearly exclusive focus on the treatment of borderline personality disorder (BPD), despite several recent commentaries in the literature that have appealed for more research on treatment of PDs other than BPD. Other limitations that affect research on treatments of Axis and II disorders include a short-sighted focus on pre-post therapy change to the exclusion of follow-up change. …
