Work design, anxiety and depression: A call centre case studyMphuthi, Faith Lerato 23 May 2008 (has links)
This research study explores the possible relationships that may exist between the work
design, level of anxiety and depression in South African call centres. By investigating the
work design of a call centre and exploring its relationship to anxiety and depression will
help to achieve this. Variables that will be looked at in this research study are work
design, anxiety and depression.
Our sample comprised of call centre agents. The agents were came from one inbound
and one outbound call centre. It was then realized during the analysis of the data that
there is no significant difference between the two call centres therefore the two samples
were merged into one sample thus increasing our sample size to a total of 56 respondents.
Pearson correlation analysis revealed that significant positive correlations exist between
all the variables, work design, level of anxiety and depression. It was also proven that the
higher the JCI score the lower the anxiety and depression levels. Additional correlation
tests were conducted to see whether there is a relationship that exists between JCI subscales,
anxiety and depression. Results showed that not all of the sub-scales of the JCI
show a significant correlation with Anxiety and Depression. Only Autonomy and
Feedback to some degree correlate with Anxiety (r = 0.38; p = 0.004 and r = 0.26; p =
0.053). Variety and Authority correlated significantly and positively with Depression
(r=0.38; p = 0.004; and r = 0.32; p = 0.017). These results indicate good support for this
research study, illustrating that the manner in which work is designed will have an effect
in the anxiety and depression levels experienced by the employees.

Quantification of Upper Extremity Physical Exposures of Materials Handling Tasks in Seated and Standing ConfigurationsCudlip, Alan Christian 28 April 2014 (has links)
Prolonged periods in sitting or standing may negatively influence worker health. Integration of sit-stand workstations has attempted to mitigate these deleterious effects, and has generated positive results in terms of postural discomfort, injury risk and worker fatigue. Identification of how identical tasks are affected by sitting and standing is necessary to take advantage of loading differences between these configurations. The purpose of this research was to determine if differences in workplace configurations between seated and standing postures created changes in posture or muscular activity levels during manual materials handling tasks. Twenty male and twenty female participants performed four manual materials handling tasks: a 40N static push, a 40N static pull, a weighted bottle transfer set at 15% of the participant’s maximal arm elevation force, and a light assembly task in sitting and standing. Upper extremity electromyography was collected at 8 sites, and changes in local joint moments and body discomfort were calculated. Interactions between task and sit/stand configuration resulted in increases of up to 500% in some joint moments, 94% in EMG activity and 880% in some local body discomfort regions when tasks were completed in sitting. A main effect of sitting appeared primarily in joint moments and muscle activity, and generally resulted in increased loading in sitting. Important exceptions existed, which included resultant wrist joint loading 8.2 times larger in standing, and foot/shank discomfort increasing by up to 609%. Task differentially affected all EMG outputs, as well as most local joint moments and body discomfort regions. Future recommendations regarding upper extremity exposures during manual materials handling tasks should consider placing workers in standing postures instead of seated ones to minimize musculoskeletal loading to the upper extremity. In addition, the effects of task and sit/stand configuration should be considered in order to leverage differences between these positions, with tasks in standing generally resulting in decreased musculoskeletal disorder risks.
