In addition, in accordance with the model proposed by Karasek [ 9] for studying job strain, values in each dimension were categorized by the median as low (≤median) or high (>median), which yielded combinations of low or high demand and low or high control.
In our earlier work [ 6, 30] the 4-point Likert scale from Strongly Agree to Strongly Disagree made the choice of cut point simple - nurses who had reported Strongly Agree and Agree for a contextual dimension were categorized as high, and those reporting Strongly Disagree and Disagree were categorized as low.
Size of rotator cuff tear (largest dimension) was categorized as large (>3-5 cm).
For every patient, each dimension was categorized as either high (i.e. above median) or low (i.e. below median).
Size of rotator cuff tear (largest dimension) was categorized intra-operatively as small < 1 cm, moderate (1-3 cm)., large (> 3-5 cm)., and massive (> 5 cm).[ 62].
Size of tear (largest dimension) was categorized as small < 1 cm, moderate (1 3 cm)., large (> 3 5 cm)., and massive (> 5 cm).. Strength, range of motion, level of pathology (existence of a full-thickness tear), concurrent osteoarthritis, and tear size were examined in relation with disability.
The mean responses to the four dimensions were categorized as <3.5 (low) and ≥3.5 (high) and the determinants were analyzed with logistic regression.
Left ventricular dimensions were categorized as follows: normal LVIDd if 22 31 mm/m, mildly abnormal if 32 34 mm/m, moderately abnormal if 35 36 mm/m and severly abnormal if ≥ 37 mm/m[ 21, 22].
In sum, these dimensions are categorized into three classifications: "Personal factors" (i.e., degree of fit with life style and passion in life), "social influences" (i.e., reference group acceptance, collective memory, and social visibility), and "VCE identification and engagement" (i.e., VCE identification and VCE engagement).
Next, strengths/challenges were categorized by dimensions of the care coordination process that emerged from the analysis.
In her chapter, movement tasks were categorized using dimensions of environmental context and action goal such that 16 distinct categories were created.
