Backgrund The number f general health staff skilled in psychlgical treatment fr depressin is limited, and learning psychlgical treatments tends t require cnsiderable training and supervisin. Relaxatin may be a relatively simple frm f psychlgical treatment. It has been frequently studied in research studies as an active cnditin and as a cntrl cnditin.

Narrative descriptin f the studies that went int the analysis The Jrm et al (2008)review cvers 15 trials, which they describe as fllws: Ten f the trials evaluated prgressive muscle relaxatin, ne evaluated autgenic training ne evaluated relaxatin imagery and three evaluated varius cmbined methds. Nine trials used relaxatin as an active interventin fr depressin, whereas six used it as a cntrl r placeb cnditin fr cmparisn with sme active treatment. The relaxatin treatment was manualised fr 11 f the trials. The number f sessins f relaxatin treatment varied cnsiderably: 5-8 (1 trial), 6 (1 trial), 7 (3 trials), 10 (4 trials), 12 (1 trial), maximum f 20 (1 trial), 21 (1 trial) and 40 (1 trial). The treatment was delivered by therapeutically trained persns except in 3 trials where it was self-administered and ne where it was unclear. The trials varied in the interventins t which relaxatin was cmpared and sme cmpared it t mre than ne ther interventin. Six cmpared 2

Participants were selected as depressed using a diagnstic apprach in three trials, a cutff n a depressin scale was used in seven trials, bth a diagnsis and scale cut-ff in fur trials and ne study did nt state a methd f selectin. The settings f the treatment were with in-patients, six were in educatinal settings, six were in cmmunity r hme settings, and ne was unclear abut setting. All but six f the trials were carried ut in the USA: these were frm Germany, Canada, Australia and the UK. In all f the trials, depressin was the primary diagnsis rather than secndary t a medical cnditin. Because f the varied measures f depressin used, it was difficult t describe the severity f the participants, apart frm nting that six trials required a diagnsis fr entry (Hwever, sme trials did use a diagnstic methd f participant selectin and these prduced similar effects t trials that selected participants using a symptm scale cutff). Peple with a anxiety disrder as primary diagnsis were excluded. Data n cmrbidity with anxiety symptms was nt prvided. GRADE Tables Table 1 Authr(s): Van Ommeren.

Data are available in 4 f 5 studies with a ttal f 6 drp-uts f 60 participants (handcalculated based n data prvided in analysis 1.1 (p.54) and the descriptin f the individual studies in the appendix). 2 I squared is 49%.

This Cchrane review suggested a much higher SMD (-1.35) fr very hetergenus (83%) clinician-rated data (pled data frm 2 studies) (see analysis 1.4, Jrm et al (2008) p.55). 5 Even thugh these data suggest mderate effectiveness fr relaxatin, this review fund even larger effect sizes fr (ther) psychlgical treatment (See fr example Analysis 2.1, N=9; n = 286; MSD = 0.38 [95% CI 0.14, 0.62]).

Jurnal f Affective disrders, 89: Frm evidence t recmmendatin Factr Explanatin Narrative summary f the evidence base n the scped questin There is lw quality evidence favring relaxatin ver treatment as usual in reducing depressin symptms pst treatment (N = 5; n = 136; SMD = -0.59; 95% CI, t -0.24) and in treatment respnse (N = 2; n = 52; RR [nnrespnse] = 0.28; 95% CI, 0.14 t 0.54). There is limited/very lw quality evidence favring relaxatin ver treatment as usual in reducing depressin symptms 6 mnths pst treatment (N = 1; n = 22; SMD = -0.39; 95% CI, t -0.45) and in treatment respnse 6 mnths pst treatment (N = 1; n = 33; RR [nn-respnse] = 0.43 (95% CI 0.22 t 0.86). In terms f drp uts, the evidence is incnclusive and s it is nt pssible t determine if there is a clinically imprtant difference between relaxatin and treatment as usual (N = 4; n = 122; RR [nn-respnse] = 0.72 (95% CI 0.08 t 6.7). Summary f the quality f evidence See abve text n narrative summary Data n functining were typically nt included in the trials and were nt meta-analyzed 5

6 Additinal evidence (eg related evidence that was nt scped It shuld be nted that Jrm et al (2008) review fund (a) relaxatin less effective than ther psychlgical treatments and (b) that relaxatin plus medicatin was mre effective than medicatin alne (see ftnte 5 GRADE table). The Pilkingtn et al (2005) systematic review f yga fr depressin identified 5 randmized cntrlled trials, each f which utilised different frms f yga interventins and in which the severity f the cnditin ranged frm mild t severe. All trials reprted psitive findings but methdlgical details such as methd f randmisatin, cmpliance and attritin rates were missing. N adverse effects were reprted with the exceptin f fatigue and breathlessness in participants in ne study. Balance f benefits versus harms Define the values and preferences including any variability and human rights issues Althugh there are sme data n drp-uts, data n adverse effects were nt meta-analyzed. The balance f benefits versus harm seems favrable fr relaxatin if cmpared t treatment as usual but if the chice is with ther psychlgical treatment, than the benefits will be less. Indeed if the prvider decides t prvide relaxatin rather than mre effective treatment, then this wuld be - relatively speaking - harmful. The interventin is cnsistent with the value f prmtin f individual and family members capacity and skills Althugh Jrm et al (2008) review mainly fcused n studies f prgressive relaxatin, it is nted that many scieties have their wn culture-based frms f relaxatin, such as Yga, which has an evidence basis (Pilkingtn et al, 2005) Define the csts and resurce use and any ther relevant feasibility issues The administratin f relaxatin exercises is a relative nn-sphisticated interventin that can be quickly learned. The reviewed literature invlved evaluatin f relaxatin as a multiple sessin activity, with mst studies invlving: 5-10 sessins. Prgressive muscle relaxatin was the mst studied frm f translatin, this frm f relaxatin wuld take abut 20 minutes f time t administer. The feasibility f this interventin in nnspecialized health care settings depends n the time that the prvider has available as the interventin, as tested in the literature, tends t invlve 5-10 sessins f a 20 minutes interventin. In situatins where there is sufficient staff eg when cmmunity paraprfessinal health wrkers (e.g cmmunity health wrkers, midwives, health wrkers) are available. This interventin is likely t be feasible in nn-specialized health care settings Implementing these interventins may be dne in grup sessins (mre cst-effective) 6

7 Final recmmendatin Relaxatin training may be cnsidered as treatment f adults with depressive episde/disrder. In mderate and severe depressin, this interventin shuld be cnsidered as adjunct t antidepressants r structured brief psychlgical treatments. Strength f Recmmendatin: STANDARD Limitatins The cmparative effectiveness f relaxatin training versus ther psychlgical r pharmaclgical interventins was nt assessed. Update f the literature search June 2012 In June 2012 the literature search fr this scping questin was updated.
