The Reliability of Arousal Threshold During Sleep

Thirty-five subjects from two independent studies were awakened at EEG-defined periods during the night with 1000 Hz ascending tone series. Awakenings were made five to eight times per night during stage 2, stage 4, or REM sleep over a series of nights in good and poor sleepers. Reliability was assessed within stage, within night, between stages, and between nights. Good and poor sleepers did not differ in either depth of sleep or reliability of arousal threshold and were thus pooled in the analyses. From night to night, the most consistency was seen in stage 4 (r=.74), although REM reliability (r?₁= .49) and stage 2 reliability (r?₁= .50 and r?₁= .69 in the two respective studies) estimates were also greater than zero. Early sleep onset and morning arousals were more variable. Reliability estimates on arousal thresholds taken within the same night for stage 2 were r= .64 and r?₁= .77 for the two studies and r= .96 for REM. The depth of sleep was not correlated with awake auditory threshold. It was concluded that five or six carefully placed arousals could give a good estimate of an individual's usual arousal threshold.     

Bounds in the Sensitivity of BioMEMS Devices for Cell Detection

This paper presents an ongoing effort to characterize performance and reliability of micro electromechanical systems used for biomedical diagnostics (BioMEMS). In order to study the interactions of human osteosarcoma (HOS) cells with BioMEMS devices, cultures were performed on silicon (Si) surfaces as well as silicon surfaces coated with 50 nm of titanium (Ti). Cell spreading on the surfaces was observed over time for up to 2 hours. It was seen that titanium coated silicon surfaces have the potential to provide a better interface for BioMEMS devices, due to enhanced adherence and spreading of the cells on these surfaces. Atomic force microscope (AFM) cantilevers were used as cell detection sensors. These cantilevers were coated with 50nm of titanium metal to provide a cell friendly surface. Theoretical models were then developed for the prediction of the vibrational responses of the AFM cantilevers before and after cell attachment. The models were used to relate the experimentally observed changes in frequency to the number of cells that are attached on the cantilever. The bounds in the possible frequency changes were determined within a theoretical framework. From experimentally calculated values for the mass of cells, random number simulations were carried out to determine the probability of cell attachment as a function of the change in resonance frequency of the cantilever sensor. The implications of the results are then discussed for the future reliability modeling of the sensor.     

Factor Structure, Reliability, and Validity of the Pain Catastrophizing Scale

The Pain Catastrophizing Scale (PCS; Sullivan et al., Psychol. Assess. 7, 524–532, 1995) has recently been developed to assess three components of catastrophizing: rumination, magnification, and helplessness. We conducted three studies to evaluate the factor structure, reliability, and validity of the PCS. In Study I, we conducted principal-components analysis with oblique rotation to replicate the three factors of the PCS. Gender differences on the original PCS subscales were also analyzed. In Study II, we conducted confirmatory factor analyses to evaluate the adequacy of fit of four alternative models. We also evaluated evidence for concurrent and discriminant validity. In Study III, we evaluated the ability of the PCS and subscales to differentiate between the responses of clinic (students seeking treatment) and nonclinic undergraduate samples. Also, in the clinic sample, we evaluated evidence of concurrent and predictive validity for the PCS. The internal consistency reliability indices for the total PCS and subscales were examined in all three studies. Limitations and future directions are discussed.
