fa Validation of a modified McGill Pain Questionnaire for orthodontic patients ارتودنسی Orthodontics پژوهشي Research <p> <strong>Objective:</strong></p><p>  To assess better and more efficiently the aspects of pain experienced by adolescent orthodontic patients, the McGill Pain Questionnaire-Short Form (MPQ-SF) was modified (MMPQ-SF) and validated. </p><p> <strong>Materials and Methods:</strong> </p><p> Internal and external expert panels developed a MMPQ-SF with 15 descriptors and 4-point Likert severity scales (MMPQ-SF15). Seventy-five subjects undergoing orthodontic treatment gave informed consent. Sixty-one subjects completed the MMPQ-SF15, a visual analogue scale (VAS), and the present pain index (PPI) 24 hours after an orthodontic visit. Respondents were grouped by gender and treatment stage: initial (15 female, 7 male), middle (10 female, 7 male), and end (16 female, 6 male). MMPQ-SF, VAS, and PPI scores were compared by Spearman correlation analysis. Underlying constructs were explored by factor analyses. Construct validity of the MMPQ-SF was tested by analysis of variance. </p><p> <strong>Results:</strong></p><p>  MMPQ-SF15 and VAS (r  =  0.78, r2s  =  0.61, P < .0001), MMPQ-SF15 and PPI (r  =  0.84, r2s  =  0.71, P < .0001), and VAS and PPI (r  =  0.70, r2s  =  0.48, P < .0001) were correlated positively and significantly. A two-factor solution (localized and generalized/emotional pain Kaiser-Meyer-Olkin  =  0.88) showed that 11 descriptors (MMPQ-SF11) accounted for 64% of response variability. Generalized/emotional pain values were significantly higher during the initial stage of treatment compared to the middle (P  =  .011) and end stages (P  =  .014). <strong></strong></p><p> <strong>Conclusions:</strong></p><p>  MMPQ-SF, particularly MMPQ-SF11, demonstrated utility in assessment of localized and generalized/emotional aspects of pain in adolescent orthodontic patients and correlated well with VAS and PPI. Future application of the MMPQ-SF11 to measure orthodontic pain more specifically could lead to more appropriate management of this important facet of therapy. </p><hr><p></p><p> <strong>Source: </strong>The Angel Orthodontists</p><p><a href="http://www.angle.org/doi/abs/10.2319/110812-859.1" target="_blank"><font color="#0000ff"> Full Text</font></a></p> Orthodontic pain, Human, Adolescent 0 0 http://idai.ir/browse.php?a_code=A-10-32-2029&slc_lang=fa&sid=1 Laura R.
