For a control or for a panel ?
What's wrong with

ScrollBar_SetAttribute (panel,scrollbar,ATTR_SB_WIDTH,nuValue);

There's a really good example in
MeasurementStudio\cvi\samples\userint\custctrl\scrollbar.
Not so sure about thickness of panel scrollbar, SetPanelAttribute(panelID,ATTR_SCROLL_BAR_SIZE,variable) only seems to take VAL_SMALL_SCROLL_BARS or VAL_LARGE_SCROLL_BARS

The best way to change this (along with other scroll bar attributes) is to load the scroll.fp file that is an included instrument driver with CVI 6.0. The location of the .fp file is C:\Program Files\National Instruments\MeasurementStudio\CVI\toolslib\custctrl
There is a function ScrollBar_SetAttribute you can use from there.
Of course, you can still use ATTR_SCROLL_BAR_SIZE with SetPanelAttribute for panels, or SetCtrlAttribute for controls like textboxes.
