The purpose of this study was to design a valid and reliable instrument—the Ralston Repertoire Difficulty Index (RRDI)—to measure the difficulty of solo vocal repertoire. Another aspect of this study was to determine the RRDI's ability to be used by voice teachers of all experience levels and to discriminate songs' difficulty into levels. Seven criteria—range, tessitura, rhythm, phrases, melodic line, harmonic foundations, and pronunciation—were incorporated in the instrument. The RRDI was tested by 34 postsecondary voice teachers. Results of the study showed that each criterion was significantly related to one overall rating established by Boytim (1982). The results also indicated high validity and reliability, and analyses revealed that the RRDI discriminated across difficulty levels and was used similarly by teachers of all experience levels.

Abstract BackgroundChildbirth Experience Questionnaire (CEQ) was developed in Sweden to assess the childbirth experience in multiple dimensions. It has been translated and validated in English, Spanish, Chinese and Persian with the aim to evaluate childbirth experience reliably. This study aimed to validate the Finnish version of the questionnaire, CEQ-FI.MethodsPrimiparous women who had given birth in Tampere University Hospital between January and May 2019 were included in the study. Women planning a cesarean delivery, delivering preterm, or women whose children were transferred to neonatal care were excluded. Eligible 450 women were mailed the questionnaire one month postpartum, and those who completed the questionnaire were mailed it again six weeks postpartum. Test-retest reliability was evaluated by computing kappa coefficients for the two responses. Background data was collected from patient records and used to perform known-groups validation. Internal consistency was assessed by calculating Cronbach’s alpha.ResultsOne hundred seventy-five women returned the questionnaire. Internal consistency and test-retest reliability were good. Women with known risk factors for a negative childbirth experience scored lower in the questionnaire, as expected.ConclusionCEQ-FI is a valid and reliable instrument in measuring childbirth experience also among Finnish-speaking women.

The purpose of this research was to develop a questionnaire that measures students’ self and co-regulated learning processes during science learning. An instrument named Co-regulated Strategies for Learning Questionnaire (CRSLQ) was developed, and its validity and reliability were analysed. Factor analytic evidence from a sample (n=214) of science students indicated that the 21 items CRSLQ consists of four constructs: monitoring, help-seeking and help-giving, efforts regulation, and planning. Cronbach’s Alpha (α) coefficients were calculated for the reliability of CRSLQ scales which ranged from 0.87 to 0.92 and 0.95 for the entire questionnaire. Additional analysis with a second sample (n=40) showed that CRSLQ was an effective instrument for measuring co-regulated learning strategies during collaborative science learning. According to these results, the CRSLQ can be used as a valid and reliable instrument in science education. Key words: collaborative learning, co-regulated learning, efforts regulation, help-seeking and help-giving, monitoring, planning, science learning, self-regulated learning.

Background:The lack of specific prosthetic-related outcome instruments for Spanish amputees must be addressed.Objective:To elaborate a culturally equivalent version of the Prosthesis Evaluation Questionnaire in the Spanish language.Study design:Cross-cultural questionnaire validation.Methods:Two-step process for cultural adaptation: forward and backward translations of English original and Spanish translated versions; assessment of both construct and criterion validity and reliability in a group of vascular amputees.Results:A total of 61 patients were recruited, 44 men (72.1%) and 17 women (27.9%), with a median age of 71.1 years (standard deviation: 7.7 years; range: 51–87 years). In the Prosthesis Evaluation Questionnaire–Spanish, the lowest scores were for gait and frustration, and the highest scores were for noise and stump health. Internal consistency of the questionnaire was acceptable (>0.70) for four of the scales used in the Prosthesis Evaluation Questionnaire but poor (<0.50) for the scales relating to appearance and stump health. Correlations with the quality-of-life levels as measured by the Short Form–36 were positive and mostly significant.Conclusion:Prosthesis Evaluation Questionnaire–Spanish could assess the quality of life in patients who have undergone vascular amputations and then been fitted with a prosthetic limb. The questionnaire shows adequate criteria validity when compared with other instruments for measuring quality of life.Clinical relevanceThe Prosthesis Evaluation Questionnaire–Spanish could be a valid and reliable instrument for assessing adaptation to prostheses in vascular amputees. The questionnaire adds information relevant to the patient and the physician and may identify cases with poor expected adaptation to the prosthesis.

Contemporary arias in English are too often excluded from student repertoire because they are perceived as being overly complex atonal works that are too challenging for the student. In order to counter this misconception, voice teachers should foster curiosity within students to seek repertoire with an open mind. Exploring music of living composers such as Daron Hagen can ignite student interest in contemporary art song and opera literature that expands the realms of what is thought to be traditional or appropriate vocal repertoire for students seeking a professional singing career.
