Validity and Reliability of the Turkish Version of the Low Back Activity Confidence Scale (Lobacs)

Patients will be recruited from the Outpatient Department of Physical Medicine and Rehabilitation, Kestel State Hospital, who have been diagnosed with mechanical LBP for the past 3 weeks (physical examination, neurological examination, spinal radiography and laboratory tests and other causes of LBP were excluded) and who have agreed to participate in the study. Sociodemographic data of patients who gave written informed consent will be recorded to ensure anonymity. Although no consensus has been reached on the cross-cultural adaptation of the questionnaires into different languages, this study will use the guidelines for self-report measurement provided by Beaton et al. Following the formation of the expert committee, the scale will be translated and the pre-form back-translated. Comparisons will be made with the translated versions and the final version of the scale will be created by taking into account the opinions of the preliminary group of participants.

The reliability, test-retest reliability, face validity and content validity of the scale will be assessed by the expert committee. In order to assess the concurrent validity of this scale, all participants will also complete the 'Oswestry Low Back Pain Disability Questionnaire' and the 'Quebec Low Back Pain Disability Questionnaire', which have been previously validated and reliable in Turkish.

The Oswestry Low Back Pain Disability Questionnaire consists of 10 items that assess activities of daily living. These are pain intensity, personal care, lifting, walking, sitting, standing, sleeping, social life, travelling and degree of change in pain. Each item has 6 options ranging from 0 to 5 points (12). The Quebec Low Back Pain Disability Questionnaire consists of 20 items assessing activities of daily living. Each item has 6 options ranging from 0-5 points.

The aim of this study was to evaluate the validity and reliability and the Turkish version of the Low Back Activity Confidence Scale (Lobacs).

Treatment and study plan

Low Back Activity Confidence Scale (Lobacs)

Diagnostic Test

Confidence Scale (LOBACS) is a self-report questionnaire designed to assess an individual's level of confidence in performing various physical activities involving the lower back region, to evaluate their perceived functional ability, and to assess the impact of low back pain on their daily life and functional performance.

Primary outcomes

Low Back Activity Confidence Scale (Lobacs)

Time frame: baseline

The Low Back Activity Confidence Scale (LOBACS) is a self-report questionnaire comprising 15 items and three subscales: Functional Self-efficacy (FnSE), Self-regulatory Self-efficacy, and Exercise Self-efficacy (ExSE). Its purpose is to evaluate an individual's perceived functional ability and the impact of low back pain on their daily life and functional performance. The questionnaire employs an 11-point Likert scale, ranging from 0% (no confidence) to 100% (complete confidence), with 10% increments for each point. Scores can be calculated globally (e.g., average score of all items) or for specific domains (e.g., average score of items 1-7 for FnSE subscale). The total score can range from 0 to 100, where higher scores indicate greater self-efficacy.
The Oswestry Back Pain Disability Questionnaire

Time frame: baseline

The Oswestry Back Pain Disability Questionnaire comprises 10 items that inquire about various daily activities, including pain intensity, self-care, lifting, walking, sitting, standing, sleeping, social life, traveling, and the extent of pain-related changes. Each item presents six response options, scored on a scale of 0 to 5 points.
The Quebec back pain disability scale (QBPDS)

Time frame: baseline

The Quebec Back Pain Disability Scale consists of 20 daily activities that can be categorised into 6 types of activities: Sitting/standing, Walking, Moving, Bending, Bed/resting, Handling large/heavy objects. For each activity there are 6 response scores on a Likert scale from 0-5 (0 = no effort, 5 = unable). If the person feels really bad, they give it a score of 5. If they feel good with no problems, they give it a score of 0.
