Primary Outcome Measures
NameTimeMethod
Change in Patient Visual Analog Scale Score for Pre-injection AnxietyWeeks 2, 3, 4, 5

The primary endpoint of the study was a change in patient self-reported 100 mm (10 cm) Visual Analogue Scale (VAS) score for pre-injection anxiety. VAS scale (min=0- max=100 mm (10cm)) 0= no anxiety; 100 mm (10 cm)=very severe anxiety.

Data from Weeks 2 and 3 were combined and averaged to obtain a single value as both weeks a 30 gauge needle was used for injection. The 30 gauge needle VAS mean refers to the mean for pre-injection anxiety for that needle size.

Data from Weeks 4 and 5 were combined and averaged to obtain a single value as both weeks a 25 gauge needle was used for injection. The 25 gauge needle VAS mean refers to the mean for pre-injection anxiety for that needle size.

Visual Analog Scale Score for Post-injection PainWeeks 2, 3, 4, 5

The primary endpoint of the study was a change in patient self-reported 100 mm (10 cm) Visual Analogue Scale (VAS) score for post-injection pain.VAS scale (min=0 - max=100 mm (10 cm)) 0= no pain; 100 mm (10 cm)=very severe pain.

Data from Weeks 2 and 3 were combined and averaged to obtain a single value as both weeks a 30 gauge needle was used for injection. The 30 gauge needle VAS mean refers to the mean for post-injection pain for that needle size.

Data from Weeks 4 and 5 were combined and averaged to obtain a single value as both weeks a 25 gauge needle was used for injection. The 25 gauge needle VAS mean refers to the mean for post-injection pain for that needle size.

Secondary Outcome Measures
NameTimeMethod
Fear of InjectionWeeks 2, 3, 4, 5

Secondary endpoint was assessment of fear of injection based on patient questionnaires completed prior to each injection. The patient will respond to each statement on a scale which ranges from 1 (almost always) to 4 (almost never).

Data from Weeks 2 and 3 were combined and averaged to obtain a single value as both weeks a 30 gauge needle was used for injection. Mean describes fear of injection for the 30 gauge needle.

Data from Weeks 4 and 5 were combined and averaged to obtain a single value as both weeks a 25 gauge needle was used for injection. Mean describes fear of injection for the 25 gauge needle.

Perception of NeedleWeeks 2, 3, 4, 5

Secondary endpoint was assessment of the perception of the needle based on patient questionnaires completed after each injection. The patient will respond to each statement on a scale which ranges from 1 (strongly agree) to 5 (strongly disagree).

A total of 6 statements were given to the participant the more strongly the participant agreed with the statement, the more favorably they perceived the needle.

Data from Weeks 2 and 3 were combined and averaged to obtain a single value as both weeks a 30 gauge needle was used for injection. Mean describes perception of the 30 gauge needle.

Data from Weeks 4 and 5 were combined and averaged to obtain a single value as both weeks a 25 gauge needle was used for injection. Mean describes perception of the 25 gauge needle.
